I'm vegetarian. Have been for about ten years now. Even if this means going to France and eating mostly couscous, or going to Japan and eating mostly ice cream, it doesn't bother me. I've eaten a lot of good things, a lot of weird things, and as long as vegetarian meatballs and buffalo wings continue to be produced, I will be content to never eat meat again for as long as I live.
That said, when you're vegetarian, there's also a small "coming out" that garners reactions-- but there are only two. It usually happens when I'm eating with a group of omnivores that I am acquaintances with. They'll see me ordering or eating something without meat, and ask if I'm vegetarian. "Yep", I'll say, wanting to get on with whatever conversation we were having. But it can't end there. People usually ask why I'm vegetarian, and I'll give a short answer. They process this, and then the perpetual two responses come. Number one: "I was a vegetarian for ___ years." "I don't eat red meat." "I only eat things that are grown locally." etc. So they're not vegetarian, but they're trying to show that they relate to my choice in some way. Number two is something like: "I could NEVER be vegetarian!" "But steak is soooo good!" "You mean you don't eat ANY meat?" and so forth. They seem to want me to admit that yeah, I have tripped up and had a few bacon cheeseburgers-- but the thing is, I never have. They seem frustrated, and are left grasping at...what, exactly?
I was discussing this with my mom, a "pescatarian", someone who eats fish but no other meat. She described the two responses as "I'm good like you" or "You're bad like me". The moral judgement is totally assumed; I don't care about judging people at that moment, just eating my couscous in peace. Asexuals are very familar with the "You're bad like me" response. ("You mean you NEVER have sex?" "Do you masturbate?" etc) However, my mom noticed, no one declares to us that they're trying to cut down on sex. Why do people think we're being holier than thou when we're really just being ourselves? Unlike vegetarianism, a choice I made to, apparently, be better than you (it's obviously all about you, by the way), we didn't choose to lack sexual attraction. Do people still feel bad and shameful for having sexual deisre? Since I don't, I wouldn't know. However, considering how messed up our culture can be about sex (oh, Gethen!) I wouldn't put it past us.
Oh yeah, I guess there is a third response, although it's not too common: "You're vegetarian? Me too!"
