Well said.
As you also mentioned, too many American leftists are now so very cowed by the perception that they are a tiny atheist minority whose only hope is to be tolerated by a sea of believers. No strong challenge from the secular left here. And this in turn negatively affects the ideological climate and narrows what is sayable in political discourse. Very bad for the Left. Extremely bad for women and queers.
American leftists, by and large, are too relativist about the matters of religion versus secular thought. A funny thing, though, is they also love criticizing postmodernists for being relativists with no regard for Reason and Truth.
