I stopped practicing superstition in all its forms.
A free-thinking friend told me recently that she regularly lunches with some people, and an Xian in the group had told her I'm a member of the Church of Satan.
I asked her if she knew where I could find a Church of Satan nearby.
A few days later she very happily told me she'd taken my query back to her lunch group and they'd howled with laughter.
When an Xian scolds you, ask if s/he knows where there is a Church of Satan you can go to.
Well, at least they seemed to have an open mind!
I say that atheism is much more reasnable.I think too much to swallow abunch of nonsense.A person I thought was a friend decided I was bad and dammed to hell because of my non belief.It doesn't happen often thankfully.
I like Penn Gillette's (Penn and Teller) response:
When someone asks me why I don't believe that we were created as humans, but instead believe that we evolved to become humans: I take a fossil out of my pocket, hold it up in front of them, and say "Fossil!"
If they still don't get it, I throw it just over their head.
Another good joke to throw at the fundies, if they bring up the "You can't see air, but you believe in air?"
I reply that although we can't see air, when we condense air we get liquid oxygen and liquid nitrogen, but when we condense God all we get is bull shit. :-)
You can quote Christine O'Donnell and say 'lets not go there'.
