Fmeh I don't think you're a bigot. I think you're talking about a subject that you don't know very much about, and I extend that 'you' to most people in the western world. Most Americans know nothing about the Middle East, or Islam, and didn't care about it being anything other than "that country with the bombs that's on the news a lot" before 9/11. So when you take a subject you don't know a whole lot about and are shown some superficially compelling negative video it's easy to believe 'OMG THEY'RE COMING TO KILL US ALL.'
It's like Fade said. You can easily find just as many horrific passages in the Old (and even New) Testament that would seem to support terrible atrocities against enemies of Christianity. I could just as easily make my own Youtube video out of that with some creepy soundtrack and splice it with clips of this guy who sits on the corner of 42nd and 6th avenue every day with a megaphone and photos of dead fetuses crying about how homosexuals and abortions are ruining the country.
But Sharia and Islam no more supports the kinds of things in this video as saying mainstream Christianity does. Yes, some evangelicals in Islam have attempted to use a corrupted version to legitimize themselves. The same thing has happened with Christianity. It just seems worse because there's a huge anti-American sentiment to it because they feel like we're trying to invade their countries and destroy their way of life. Because we are.
So I think you should really research this a bit more. You're forgiven for seeing a video that looks genuine and assuming it's representative of a belief system. But it's an edited attempt by a bigot to rationalize hatred of Islam and is no more fair a representation than claiming mainstream Christianity supports killing non-Christians as well.
