the particular group I hung out with had an overwhelming need to convert people, and couldn't resist a juicy atheist/agnostic specimen like me.

Ah, that's unfortunate.

As far as I can tell, the religious communities my atheist/agnostic church-going friends belong to consider them full-fledged members of the community no more in need of alteration than anybody else, which seems like a much more honest arrangement.

Though, of course, I have no way of knowing for sure.
