Some people don't eat meat because they don't like it or health reasons. I'm not vegan, I've been vegetarian and am pescatarian now(will eat fish and seafood) because I don't care for meat. If I get a weird bit of fat or gristle it turns me off eating for the entire day. Can't do it. Seafood seems to have less feelings than mammals in my mind as well. I'm not against meat. Animals would eat us as well. It's natural to eat meat. But factory slaughterhouses are vile places. So too egg and dairy. I think people should eat less of these things so the animals can have better conditions. That's what needs to change, not so much the act of eating meat, just better treatment for living beings.
