That video has been widely debunked. The "journalist" who made it equates any criticism of US foreign policy with being a 'radical.'
Moreover, without knowing what people of other religions feel, the stats don't really mean much. For example, it would be interesting to see what the views of groups like Orthodox Jews in relation to violence are. I believe the author of the video is an Orthodox Jew himself who previously referred to non-Jews living in Israel as 'cockroaches.'
Jesus, a benevolent preacher who taught love and peace
A failed Roman rebel who preached that anyone that didn't accept his father's message would burn in eternal hellfire. A man who claimed that slavery was a natural condition and that cities that rejected him would face a fate worse than Sodom and Gomorrah. A madman who once tossed pigs off of a cliff because they were 'possessed' and attacked a group of Jewish bankers.
On the other hand, Muhammad was a leader who fought earnestly to unite his people who had long suffered under the rule of the Persians and Byzantines. He outlawed many harmful practices, adopted legislation that afforded some measure of protection to minorities (something neither Christianity nor Judaism had done), and lead his people on to found one of the largest and most successful civilizations in history.
See? It's easy to portray things how you want them.
marry your 1st cousin, marry and have sex with children etc.
I hate to burst your bubble, but none of those things are prohibited in Christianity or Judaism either.
In fact, the bible goes to great lengths to condemn gay people and adulterers, but never once says anything bad about pedophiles.
a disproportionate amount of rape and violent-crime perpetrators
That doesn't really mesh with your argument of them being ultra-devout Muslims who follow the Quran.
Islam explicitly prohibits any form of premarital sexual conduct. Ultra-conservative Muslims consider even looking at a woman sinful.
Sharia law also punishes crime quite brutally.
