even though what they're doing is crusading against sexism, racism, patriarchy, etc., simply because no True Social Justice Warror would engage in rational debate or respond to disagreement with sensible engagement rather than outrage.

Slightly off topic, but can I ask why patriarchy is assumed to be obviously bad?

I can certainly see the negative aspects of even moderate patriarchy, and wouldn't endorse extreme patriarchy or all forms of it, but its positive aspect seems to be civilization as we know it. It makes monogamy viable, reduces the time preferences of the people in a society, makes men invested in society by encouraging them to become fathers and husbands, boosts fertility rates to above replacement, likely makes the average man more attractive to the average woman improving many relationships, results in a political system of easily scalable hierarchy, etc.
