Yes, Brian. I just read how Islamic rule influenced Spain for 800 YEARS.
They really ruined the place. Here's an article on the subject. Wiki's is too long:
Our understanding of the history of the Mediterranean is pretty much told from the point of view of Greeks and Romans. But the Persians were a sophisticated and advanced culture; in many ways as much or more than the Greek/Roman. Now a lot of that was before Muhammed; but it didn't end with the establishment of that religion. The Spanish influence was AFTER Islam was established.
Note too that under their rule, there was a religious harmony between Muslims, Catholics and Jews. That ended in 1492 when the Muslims were expelled. That's when the Inquisition began. So things were SO MUCH better under Catholic dominance- as long as you were a Catholic.
Your extreme bias on this issue is sad/ignorant and off-putting. But I don't expect it to evolve much.
Recall that Indonesia is the LARGEST Muslim nation; and we don't hear much about their nastiness. My brother and wife have been there more than once and just don't find any kind of religious issues when they're there.
