Indeed. Islamic conquest of Europe might mean no European imperialism, which pretty drastically changes the course of the modern Middle East and throws most of what Westerners think they know about "Islam" right out the window.

And no, the Christians didn't "kick out" any Muslims from Vienna during the Crusades. Given that the Byzantine Empire barred passage into Europe until 1453, how exactly would a Muslim army have made it to Vienna in the 11th century?

I said they kicked them out of Europe in the crusades. They kicked them out of Vienna in the 16th century. If the Middle East would have been so successful on their own, given that we have invented the technology for a space program and the Middle East have so much money thanks to oil, they should at least have their own space program by now. Or contributions to modern science and technology? They can afford it and they have a leg up but all they want to do is pray and live off the money they make from oil. Any techological advancement would have come from the East Asians who may have put a man on the moon by now or maybe in a few centuries. Islam, never.

Conquest, live off dhimmitude, have sons and pray.

It's nice to have a point illustrated so concisely.

I'd encourage you to think about when oil became widely available and/or exploitable for human use, and what was going on in the world at that time.

this is so bad its not worth trying to explain to you

Do you even know how much of the technology you use and rely on has its bases in Islamic countries? Hell they could say the moon landings couldn't of happened if we didn't use the math and science they helped to develop.
