As evidenced by how many different Christian denominations (more than in Europe) still existed throughout West Asia, under direct Arab Muslim rule, for over a MILLENIA.
Denied basic rights? Basic rights to minority Christian, Jewish & Zoroastrian groups was ENSHRINED in the very makeup of these states. Leaders of these communities had official roles & responsibilities reserved for them.
You simply don't know what you're talking about. You're taking a modern day story about "Arabs" & "Muslims", which is predominantly the result of 100 years of subjugation & being broken up by the West (& having Western vassals & elites imposed as ruling classes), added to the need to create unsavory impressions of them amongst Western populations in order to justify that.
And you're taking this mess & overlaying it over the previous 1300 years, without a single regard for the truth. Seriously, go get a genuine history book, or talk to a history professor who knows about the Arab & Muslim world, and then curl up in embarrassment...
