Maybe because if you compare it in its actual time and not progressive mindset of the 21st century, you will see that for its time it was tolerant.
At its least intolerant periods it was more "tolerant" than contemporary Christian Europe lands at their most intolerant. At its most intolerant it was more intolerant than contemporary Christian European lands at their least intolerant.
Especially comparing it to its Christian Counterpart, it was a lot more peaceful.
So the emirate/caliphate of cordoba never engaged in anything that could be described as "military attacks" against its non-Muslim neighbors?
During this time the christians were too busy killing of every one that was not a christian and the Catholic Church making tons of of money and wealth from serfdom.
So Islamic Spain was some kind of socialistic paradise at perpetual peace with itself and the wider world by comparison was it?
Are you seriously trying to compare 14th Century civilization to modern day civilization?
We are not talking about the 14th century we are talking about the period of the Cordoba emirate/caliphate (c756-1031). Now If you want to talk about the 14th century....Do you?
Because your comment " How can a sharia state where people werejudicially murdered for "insulting" Islam stand for "progress" is a 21st progressive ideology. And no it didn't stem from your christian buddies. It stemmed from 20th Century Progressive movement. Liberal Ideology
Then tell people like z10 not to superimpose "20th century" western concepts like "progress" on a centuries-long-gone Muslim-ruled hell hole.
