I'm not kosher or anything since I eat meat out, I don't follow the separate dishes thing, and all that stuff. But I do follow the big dietary no-no's, and that's probably because I just grew up that way. Not eating any form of pork when you're young, once you get older you're like why the **** would I want to eat that disgusting (but also kinda cute) creature? Not when there's that cow over there who I've eaten a million times before!
But these days, it's a rarity. Most of my jewish friends eat bacon too.
