Your position is that being a Muslim implies blind allegiance to a singular philosophy, and that simply does not line up with the facts.
I am not in any way defending Islam here, but your putting brilliant minds, educated in Greek philosophy and thought, in a tiny little box just doesn't wash.
But, I have no doubt that there is no amount of evidence that will change your mind, so I'll end this now.

Why should we care that dhimmi history has convinced most educated people that Christians lost Aristotle and Muslims restored him to them? Why should we care that they believe in a Golden Age of Islamic philosophy that never occurred? We should care because we should care about the truth, but more than that, because these false beliefs are actually quite dangerous, for in the malignant minds of terrorists, they justify murder. Dhimmi history confirms the sense of superiority Islamofascists feel, it sympathizes with their wounded vanity, it shares their enemies, it reminds them of their past glories, it makes them feel unappreciated, it flatters them, it makes them suspect treachery, and it tells them that they are right.
Dhimmi history has the disastrous effect of heightening the 'sense of injur'd merit' that the jihadists feel—along with Milton's Satan. The lies of dhimmi scholars are, like the borders of Islam, bloody.
