Whether or not they believe in god they are smart intellectual types and probably cohort with some atheists. Once they realized atheists could be good people too it probably changed their opinions ... just what the evil atheists want!
I know Colbert is a Catholic, but I’m not sure how firm his beliefs are lately.
Occam
Colbert’s character is a Catholic, but you surely can’t believe that Colbert himself is a Catholic. Has he self-identified as a Catholic in a bio or something? If so, I’ve never come across this. His character is a blatant mockery of the religious right, which is why so many of us love him.
