Unfortunately, Jeff W, you are an aplologist for all manner of deadsh!ts, including cheating East African runners. You are misguided, as usual.
The Ustase were, to quote the Encyclopedia Britannica, a 'Croatian fascist movement', who were 'dedicated to achieving Croatian independence from Yugoslavia' Furthermore, 'to make their state more purely Croatian, the ustaše set about exterminating its Serb, Jewish, and Gypsy inhabitants with a brutality that shocked even the Germans and occasionally obliged the Italians to intervene'. Clearly, they were a nationalist movement, and any religious concerns were secondary. The Balkans is a cess pool of ignorance, brutality, and despotism-much like Africa really.
You are a mug if you think any but the most occasional Islamic ruler has given a conquered group any slack at all. Get yourself educated here

To quote his article:
"As Muhammad had plundered his foes, so his successors also stripped the conquered areas — incomparably richer both materially and culturally than the desolate sands of Arabia — of their wealth and manpower. Almost overnight, the more advanced civilizations of the Middle East, North Africa, Persia, and Iberia saw their agriculture, native religions, and populations destroyed or plundered. Save for a handful of walled cities that managed to negotiate conditional surrenders, the catastrophes those lands suffered were very nearly complete."
Christianity and other religions, plus Western society generally, have evolved and tried to get more sophisticated and civilised. These crazy pr!cks haven't changed in 1200 years. We are still 'dal al harb', the enemy who needs to be subjugated. You are the one who needs to read more.
