Are you from a different planet/dimension or just confused or stupid?
First, who are you talking about? "Meat eaters" are carnivorous animals like lions and tigers. "Omnivores" are animals that can eat, digest and obtain nutitrition from both meat and plant material. ALL humans are omnivores.
People include meat in their diet because they are omnivores, it's what the majority of people around them do, it's affordable, they enjoy it and it's an important part of a nutritious, balanced diet.
I don't think I've ever heard anyone say, "Its [sic] ok to kill animals..." but it's basically necessary if meat is to be consumed. Humans can't swallow animals alive the way some creatures do. For your information any kind of farming or large scale food production involves the killing of animals.
Yes, vegetarians and vegans are in the minority, but then they would be since humans are omnivores. I don't believe that most vegetarians and vegans are in the least "brainwashed" but lots of the kids who post here are incredibly ignorant and seem incapable of thinking for themselves.
Those people, and ignorant, illiterate, rude fools like yourself make it difficult for ordinary vegetarians and vegans to be taken seriously.
