Veganism

How do you feel about it? I feel that Veganism is unnecessary, and almost every vegan I've come across has been very rude and pretty much everything they said, aside from opinions, was incorrect. Humans are omnivores, and I think that we should be grateful of what we've been given to eat and not try to make others feel bad about it. I do agree, definitely, that factory farms are terrible and need to be stopped. But the act of eating an animal/animal product? There's nothing wrong with it. No hate to vegans. If you feel like living that lifestyle, then go right ahead. I just feel that it's unnecessary and you shouldn't be rude about it.
