I personally don't care if people want to be vegan, vegetarians, or eat rocks.
But what enrages me is the idea of vegans that their diet is somehow more "moral" and "natural" than an omnivore diet.
Humans have evolved over umpteen millennia as omnivores. We have incisors for a reason. To rip and tear animal flesh.
So when vegans/vegetarians claim they have a natural diet, they are being unscientific. Humans have obviously adapted to eating plants and vegetables. Ditto for many other mammals.
Humans need meat to get the right vitamins. Otherwise, we need to take a B-12 vitamin supplement. There were no vitamin stores with pills for hundreds of thousands of years of human existence.
Are the vegans going to ask bears and many other critters to stop eating meat? Vegans would probably be among the first people to claim we're no different from other mammals. Then why should we not be able to eat meat while they do?
Another thing that enrages me is the fact that idiot vegans in California are trying put dogs at animal shelters on non-meat diets. Those people should be arrested and given a huge fine or jail sentence.
