Liberals and Democrats are not hostile to religion and Christianity in particular.
Not all, but many are.
Can you tell me why Hillary, being a Methodist herself, did not bolster her appearance as a person of the Christian faith? Can you tell me why Obama, being a member of United Church of Christ, did not openly refute accusations that he was Muslim rather than letting people carry on forever with it?
For my money, it’s because it doesn’t target their base.
It’s actually probably because they realized that it had no relevance to their candidacies and had no bearing on their abilities as potential presidents. As for the Muslim theory, I’m assuming he didn’t refute it because it was a psychotic conspiracy theory only believed by insane people or rightwing hacks.
…As opposed to Republicans, who (and this is an enormous pet peeve of mine) co-opt their so-called Christianity for political points.
Yes and this is worse than not pretending to be religious. The fact that liberals are accepting of candidates that leave God out of their rhetoric is more respectable than people that accept predatory and adulterous conmen like Donald Trump because he pretended to be a Christian.
