Because those lovely barbarians known as “Mohammetans” burned the library of Alexandria.

In fairness, almost all of what we know of classical Greek literature, mathematics and science is from translations and copies that came down to us from the Islamic University at Damascus. Arabic and Persian scholarship in the Middle Ages was of a very high standard, outstripping Europe by centuries. One side effect of the Crusades was to expose Europeans to their own intellectual heritage. To some extend Roman and Greek writings were seen as anti-Christian or at least in competition with Christianity during the "dark ages".

Today, it is the Islamists who are regressive and closed minded.

That is true only if you discount Byzantium which was still the epicenter of classical learning and civilization deep into the middle ages. And it should be remembered that Syria and the near-east was still majority Christian for a long time after the Muslim conquest. This is not to say that Muslim scholars played no role at all in transmitting classical scholarship. In my opinion, their role has been over-estimated.
