Where do you see "anger" in anything I said? A deep psychological test would reveal lots of projection on your part.

Yes, there was a "golden age", but it did not last very long, as a more fundamentalist version of Islam took over. Is acknowledging this "anger"?

The version of Islam dominant today in the world isn't the "golden age" version, it is the fundamentalist type. Do you deny that, too?

There were actually a lot more similarities between the three religions then, Judaism, Christianity and a "golden age" version of Islam, than there is now between the various versions of Islam, and the militant atheism and just indifference to religion dominant in the modern world.

There were not such radical differences in the way people conceived of the role of women, for one thing, and when everyone agrees religion is fundamental, there can be, and there was, lots of respectful discussions of various conceptions of what religious truth is. That won't happen today.
