Gawds, there were many stories about exactly that. It's been nearly a year but I have constantly heard about the superior morals of the left, usually in the "left-handed" compliment style of producing something some R has done. Followed by some other poster saying, "At least the left doesn't put ourselves out as morally superior!"
Usually such attempts draw examples of activity from the left that was much the same and those draw comments like, "I love it when their defense is, the other side does it too! blah blah...."
Oh, this is all true, especially the part I bolded. Of course you are going to see that a lot, it's the truth.
I just meant, I never heard about any ascendancy of the religious left. And, I am definitely not the religious left, myself. But I could have missed it. I know there was a book out written by some religious liberal guy, maybe that's when it happened.
