It's insulting to those of us who are. I don't know what you should be called, but I know what you shouldn't. Others expressed their point of view more softly. Diane, a vegetarian, said that although she strongly believes in not eating meat, she keeps her opinion to herself unless directly asked about her choice. If she feels the questioner is antagonistic she won't discuss her views at all.
Some people just like to argue.
What I eat is my business and really not up for discussion. Some pointed out that it's not necessarily the killing of an animal for food that is the issue, but rather the in-humaneness which with that feat is carried out. American Indians had the right idea, but industry and restaurants have completely changed the way we consume food. It is the factory killing that I don't agree with. But the way we slaughter animals and the disgusting conditions in which they are kept can in no way be considered necessary.
