I have a dear friend who loves rationality, reads Methods rabidly, quotes 'That which can be destroyed...' at the top of her FB profile... and still identifies as Christian. She's young and has had the kind of sheltered upbringing that makes it possible to actually believe your religion without lots of doublethink.

I expect to have her deconverted within a year or two -- I'd have managed by now if we weren't half a state apart.
