The difference in self image between a vegetarian who occasionally eats meat and a meat eater who eats mostly vegetarian is tremendous, amirite?

I've never heard the former describe himself as that. I know a ton of the latter, though.

What do you mean by self-image, do you mean attitude towards others? I don't really understand. What is the difference in your opinion?

Vegetarians and carnivores who eat meat or vegetables are neither. They are omnivores.
