Pretty sure Persia, India, and China all had great empires and knowledge well before

I said that most civilized areas conquered by Arabs during the initial Muslim expansion were mostly Christian, and they were. That would be Egypt, Syria, Mesopotamia, Armenia and the Iberian peninsula. Berbers in Northern Africa yeah, mostly weren't Christian.

The Sassanian Empire was obviously a Zoroastrian theocracy with a huge Christian population.

What does this of yours sentence have to do with what I said requires clarification.

well before Christianity was even a little sperm cell in the Judean god’s sac but sure

You do realize that this is even truer for Islam, right?

Which btw most of foundational mathematics was created in the Eastern and Persian world, not by Christians.

And as I've said already once, the Middle-East was Christian at the moment of the Arab invasion, and Iran was Zoroastrian. Thus attributing praise for any of the achievements the conversation was about to Muslims is fucking asinine.

So yeah you’re just racist and misinformed.

I've forgotten on this subject more than you ever knew.

Also how does contempt for the Muslim religion make one racist, I wonder? It's (in Sunni variants, I'll admit Shia Islam is better) every bit as worthy of contempt as the Christian religion, but without the upsides.
