The worst part about vegans is they claim to be pro-animals, and yet these same animals are only so successful thanks to their relationship with humans. You replace pastureland with whatever farms, and the same cows the vegans "set free" would be shot for damaging crops when they wander nearby. That is if they survive in the wild at all.
You never see a chicken complain about how successful its species is. Make up most of the biomass on Earth. All because humans find them tasty sources of protein. Meat eaters want to take chickens to the stars, vegans would prefer chickens go extinct because they're unnatural or something. Who is really pro-animal here?
