I don't think the point is advocating some sort of moral relativism but rather to steel-man both sides in good-faith rather than respond to some sort of caricature of each.
Yes i agree caricaturing is clearly wrong. But i am saddened by this group think that all groups of people should be given even standing as all having positives and negatives. People should be given standings based on verifiable evidence with regard to their actions. If your group is composed of bad actors, your group is bad. We don't have to treat you fair and balanced.
When a man beats up a wife, _you don't say_, well, look, she probably wasn't the easiest to live with, and he had it tough dealing with her. He is a good business man, and a pillar in the community. so look both sides have positives and negatives. (Well to be fair as a society we usually do, do this, but clearly we are wrong).
No the facts say otherwise.
