The difference between evangelicals and leftwing "postmodernists" & intersectional identity politics types is that one is based on a morality from an old book of fairytales, while the other is based on academic reasoning. The only problem is that sometimes the reasoning in the latter can be faulty, at least IMO.
Reasoning is better than having a ring in ones nose from religious indoctrination.. Even faulty reasoning can be corrected by further reasoning.
