The idea that Jews and Muslims lived in peace and harmony from the 7th to the 20th centuries is pure Muslim propaganda, like white southerners telling us that blacks and whites lived in peace and harmony before all those Yankee outside agitators showed up in Mississipi and Alabama. The Dar al Dhimmi Jim Crow-like regime Islamic law mandated was punctuated by periodic pogroms, extortion level poll taxes and the constant threat of violence. It was better than medieval Europe. But that sets a very low bar. There's a reason Maimonides was a refugee.
