We know for sure we have evolved to be omnivores. This can easily be determined based on e.g. our teeth and the length of our digestive system.

Well, of course. We don't even need science to determine that humans are omnivores. Just look around - not everyone eats meat.

Because meat is expensive, primarily. Especially from poorer backgrounds there is a culture of minimizing meat consumption and saving it for children just because of it's rarety.

That's the meat of the argument for me.

I grew up in eastern Europe. Yes, meat was more expensive 30 years ago. These days, thanks to endless subsidies, meat is way cheaper than quality vegetables and most nuts.

And yet, people choose not to eat it. Earth shattering, I know. Damn, some people really get pissed off when you make the "wrong" choice of not eating meat.

Meat is cheap where I live and about 10% of the population doesn’t eat it. It’s actually 13% according to surveys, but let’s say 10% to be safe.

I could also hunt or spearfish like I used to. Meat is easy to get. There’s no need for it though.

Meat is amazing if you’re starving because it contains a lot of stuff a hungry person needs. Kale is not going to do the same things for you. However, it’s unlikely anyone on here is starving. Meat has rapidly diminishing returns as you stop starving and have a more stable diet of plants. Eventually eating meat becomes harmful, but eating plants does not.
