Stinging regret? What about? Not sure I'm following you on that part.
I know what you mean about the self-righteousness combined with paranoia, though. All crazy fundamentalists know that everyone who's the slightest bit less conservative and observant than them (they've got it just right) is going to hell, because they're not real Christians.

Jeeze, ex-Pentecostal, huh? How weird has that got to be, looking back at your life? Being an ex-Catholic isn't nearly as exciting. I always got the feeling that half of the priests didn't really believe, anyway.
And ... wow. You could totally pull off an Amy Pond. ^.^
