Azov are fundamentally egalitarian fanatics just like the Regressive Inquisition. My brother and I against my cousin, my cousin and I against the world. They barely even cont as heretics. Putin is a genuine apostate, so the Inquisition unites with Azov against the outsider.
Problem: what about historical Christianity? It would seem they could never truly unite against Islam. Maybe a bit for the reconquista - and I wouldn't be surprised if that was more of a Monroe Doctrine thing in reality.
Perhaps it was never anything more than an anti-pagan weapon that happened to outlive its purpose.
