It’s not clear what "revisionist" means in this context, especially when pointing to Dhimmi.

I’ve never heard of it before today. I’m aware that Jews and Muslims live in Iran today. There is historical evidence, including written accounts, that some arrangement (Dhimmi?) existed over 1,200 years ago—whether social, legal, cultural, or, most likely, a combination. Under this system, the religions coexisted without the overtones of genocide within their communities.
