You know what? I thought about things to debate based on your reply but

This is simply the explanation we are given in similar works of fiction. If you don't like it, go complain to book and comic authors

If this is one of the first things to explain, you haven't read enough novels. I'll just say this: Most stories that have a "system" setting, either everyone's system is generally the same, or only the MC has one. The only difference of the everyone is the "tier" of the MC's skill or the exponential increase of skills. This is actually the first story I've read that everyone has a system but NO ONE had a skill. With that based on experience reading there isn't anything further to discuss

All in all is it ok to not eat meat? No because our bodies have developed to be an omnivore. Do I necessarily mean every meal should be eaten with "red meat", no. There are poultry and fish as well. CAN you survive without meat? Yes, you could live on pills and grains (to push digestive system) and get all the nutrients you need which eliminates "bad factors".

The main point I've been trying to point out is that meat consumption isn't unhealthy. Eating high volumes is unhealthy, to a point I never remember a single pyramid (or other diagram) that equated meat as a high serving. ¹The food pyramid of 2-3 servings of "protein" is actually a maximum value where fruits of 3-4 were a minimum value [¹ wiki].
²Even Harvard has done tests to determine meat isn't unhealthy, it's our consumption value that is. [² https://www.health.harvard.edu/staying-healthy/whats-the-beef-with-red-meat]

So to the main point is there are studies that suggest that eating plants build up chemical value in your system and thus contribute to cancer and other medical conditions. Eating fish increases mercury in your system. So, do we avoid meats, fish, AND plants? Of course not. The healthy thing to do is actually limit to the correct values you are supposed to consume while switching between protein alternatives sometimes. (meaning not 100% - red meat, plant type, fish, nuts, or poultry).

This debate in itself has always maintained a side of unbiased. I'm not trying to push meat but "healthy levels" of meat. I'm not saying you need it every day, but because of body evolution every so often at least. Which can also be worded as "You need meat in your diet at least once in a while because this is how our bodies evolved to be". The two sentences make the difference depending on the audience reading them. The first undervalues the meat (if you aren't objective), where the 2nd overvalues meat. This is targeting a specific conclusion by using words to influence an objective persons opinion. Just like giving one sided negatives of meat but not the negatives of alternative consumption. I've never really seen a test that targets "the best option" objectively but tons of "why this is bad/good".
Keep in mind food corporations influence media, politicians, and "empirical data". Like there was a driving test that was once done to show how habitual marijuana consumers are "dangerous drivers" but was revealed to have made the driver in the virtual test to have driven a vehicle with the response of an 18wheeler. When he still didn't crash they used a forced crash scenario. So why would WHO say meat is bad? Socioeconomics and bribery could both reasons. Or the report is a fact driven article to lead a consensus of their bias.

"As the atmosphere is slowly changing, humans change with it. They are slowly becoming more proficient at using Mana to become stronger and gain additional abilities. Humans that adapt themselves before others (or better then others) are called "awakened" / "hunters" / "raiders" in these kinds of stories."

It's been 14 years getting used to the dungeons, 2 year of which (time MC spent in Isgard) was when "large monsters started to appear more frequently" (chpt 2). The world developed their information enough to make it a major course in college, which then progressed to the point where "it'll be hard to find a school now that doesn't teach those classes".(monster biology and dungeonology).
They should have progressed to the point where people have skills especially since cyclopes, minotaur, and dungeons increased frequency by the time he disappeared. In every novel that's come out they are considered at least B-rank and go past S-rank.
According to your own slipshod explanation that talks about progression; the earth, by your standards of evolution, is already past the midway point of adaptation. Being on the back end of evolution, how come NOT ONE PERSON HAS A SKILL?
Even if you group skills categorically, there would still be skills that DON'T require mana. Like warrior or archer type skills.

fuckin runs off so he cant be counterclaimed... That's a hard strategy to beat

honestly Its not that they forget but that by chapter 30 they fuck the future so bad that even major events change (dates/order/ect) making their careful planning nonstop to be worthless

And he's pretty friggin OP right now.. He just isn't showing off.

enough guts to call himself a girl to get revenge

when the father sees the trick of the old man, then the father pulls an ambiguous answer. confirms and solidifies sons position, but at the same time gives him a life risking trial (which every candidate needs to pass anyways)

so i saw the hair and was ready to see another one of those hot servants and was thoroughly surprised

I'd say most are weak. The ones suppressing citizens are most likely the bottom of the barrel doing trivial tasks. You wouldn't send your strongest to kill ants especially when you have already suppressed the area would you

they did say to behead the enemies on introduction

especially if 80% of chapters keep being people standing around gawking at MC

the MC is the offspring of someone powerful that isn't worth the trouble of provoking, but at the same time the land around is prosperous

right. That explains why he has multiple powers and even able to continue to get them, but not why NO ONE else doesn't have even 1. Take note that this is chpt 50. Even among the most powerful people, NO ONE except the MC has displayed a power despite operating under the same system.

We get MC is special, but not why, not a single awakened hasn't developed at least 1. By now at least a "hero" type character should have appeared. (maybe being blessed by being a rare 1 in 1billion to have 1 power that increases potential). It's not like he showed up with otherworldly knowledge on the FIRST day of invasion. It's been years. Enough for humans worldwide to set up a proper reaction force with the knowledge of weaknesses of regular monsters (dark magic monsters have appeared only since he returned)

Trans fats are typically added to foods as a means to extend its shelf life. Food companies have done many things in this regard to maximize profit like also spraying meat with carbon dioxide to prevent meat from "browning" and looking unappealing. Its not about eating meat is bad, its about the way it's produced. Because cows eat hay, and the grass for hay may have been grown in chemicals to prevent bugs from destroying the crop, now the cow eats pesticides that may have not had their half life expired. Because this cow has poison in it, does that make meat bad or the way it was acquired bad?

This is what the second part was talking about how facts can be used to make a narrative that fits an agenda.

If you go to the website and keep in mind that they are talking about water the whole time, you will understand how facts can be used to push an agenda.
Btw
Dihydrogen Monoxide
Di =2, Hydrogen = H..... So 2 H's abbreviated as H₂
Mono = 1, Oxide = oxygen compound bonded to another element, Oxygen = O
H₂O₁ = H₂O ("₁" is dropped because it's unnecessary)
H₂O is the chemical composition of water

Honestly its hard for translators. There are words that we as english speakers use to correlate things like big vs tall. Although big is tall, tall refers to height where big refers to anything that is more than average. We also have words that correlate to the same root where the outcome is different Erosion/corrosion. Both are the breakdown of something, but erosion is displacement where corrosion is the change of properties

Not quite. Psychopaths only lack emotional connection. And most adults have learned to reflect emotions fyi. They aren't necessarily dangerous either. But if they are aggressive, they WILL cross worse lines.

was looking for this comment b4 i said anything

waiiitttttt a minute...... Aren't they already?

😂🤣😂🤣😂🤣🙃.
