Well, even if you were vegan, you couldn't put dairy products into your mouth anyway: vegetarians only not eat meat; vegans don't eat anything that comes from an animal, including dairy products.
Trust me, I know, my cousin and his wife have become staunch vegans in recent years . . . and yes, they're among the kind that act like you are scum of the earth for eating animals.
I know they say dairy and meat are actually the worst food groups for you, but beavershomeit, they're two of my favorites!
