Also, the way I treat all religious pushing is to push back roughly as much - say while setting up a play date someone says How about Sunday after church, I might say well, we're atheists, so anytime Sunday is fine, how's about 2:00? And when shall I come pick them up? Whereas if someone comes to my door with christian tracts, I say Oh, yes, I'd love to talk, I'm an atheist, you can try to convert me and I'll try to convert you. Our conversations rarely last very long and they hardly ever come back.
I once spent about a half hour with one of those guys with a huge cross - great story but too creepy, threadwise, I mean!
