Vegetarian

I dislike them.
They are a group of people view their eating habits as a kind of moral and push it to others.At least all vegetarians I met have this kind of behavior.
They feel superior than others for what they eat.They claim being vegetarian is more healthy ,but they can't proof being vegetarian can living longer obviously.
