You know, being a vegetarian doesn't mean I eat only vegetables. I don't take and vitamins or tablets, I am perfectly healthy, more so infact than I would be if I ate meat.
When did I say eating a steak was unhealthy? It isn't great, but it isn't going to hurt you
Meat is not a necessity in a human diet. I don't know where you came up with that. You can get protein from many other sources than flesh. Sure we can eat meat, but that might not be the way we evolved. True carnivores do not cook their meat, and they have sharp teeth, not flat grinding teeth like we do.
Are you retarded?
Unless you have invented some new kind of food, you need to kill the animal, and unless you did something to it first, that does cause pain
I don't see anything wrong with eating meat, and I don't condemn those who do.
