…and you could do the same thing and eat exclusively from the animal kingdom too.

If you don’t want to eat anything from the animal kingdom for your own reasons, cool. But when you start saying anything about what other people eat, imo you are no different than someone saying their religion/beliefs are best. Just don’t.

Humans are omnivores and always have been, society and technology today has only recently allowed humans to strictly become vegetarians on any kind of scale. Specific eating habits for moral reasons is a thing people who aren’t poor in first world countries have the privilege of doing. People in 3rd world countries/poor people are simply going to eat whatever is available to them.

Again, no one is wrong here, until one starts advocating that their way is best or better.
