On a similar note, I once had a fellow respond to a Gamers seeking Gamers ad by writing (paraphrased), 
"I saw your ad in GSG.  I don't smoke or drink or do drugs, and I don't put up with people who do, or who swear.  Do you do these things?"
Well, as I said, sometimes a player will drink a single beer during an evening of gaming, and sometimes I have players who go out on the stoop to smoke, and if I'm playing a loud crude guard, then she'll use loud crude language.  I wrote the guy back and told him this.
Turns out he'd been burnt by a group of foolish drunken stoners who replaced roleplaying with swearing, and he was looking for a different group; the way we played, he said, didn't sound like it'd be a problem.
Err...right.  Glad to know we weren't a problem.  I was so turned off by his initial approach to me that I never wrote him back.
It is, of course, perfectly reasonable to look for a group with the same vice tolerance as your own.  But I'd suggest being polite and nonselfrighteous when you go looking -- otherwise, you may get turned down by a group on account of your attitude, even if you have no problem with them.
