I do not mind vegetarians. It doesn't bother me if that is how you choose to live your life.
What sometimes grinds my gears is when veggie eaters try to attempt to convert me. It happens often, and we get into a fight about morals. We have different outlooks on life and we make our own decisions on life.
However, being a veggie is a good thing, especially if you feel better about yourself because of it.
