I don't think that's true at all. How many Muslims have you directly spoke to who have said they have no problem with it? Many Muslims will say that such things are against Allah. People will use things subjectively for their own purpose.
The challenge with the Muslim religion is that Sharia Law is quite brutal and strict, and I guess culturally those who want to take things out of context use that as their justification for being brutal themselves (but not in the same way, in a criminal and non-Sharia way).
This is what happens when Religion is government.
If Christianity was government like in the dark ages, people would be burnt at the stake, you would have Christian mobs going around killing, hanging, drawing and quartering, racking, cutting off the sinning part of a person, etc. So how come that has nothing to do with Religion? Christianity is violent when it too is a Theocracy. In fact the Christian's and their Crusades were extremely prolific and violent.
The issue is with Theocracy rather than Democracy. As for the most aggressive country in the world, it's America. The War on Terror, has it brought peace? No, but it brings lots of gun sales. To think that it has nothing to do with business is ignorant. America is not a Theocracy, so such things as corruption, over making money, mean nothing.
It seems all the terror started when we had this war on terror. What about the war on drugs, did that work? No. And now that has changed to more of an acceptance. I'm still weighing up whether that is good or bad.
What if, just what if, you are all being duped, so that you support a war on terror (and what exactly is 'terror' now associated with?) Financial interest when in the hands of a country will do ANYTHING to make sure it can keep going. Manipulation of the public has been studied since before WW2. We accuse ISIS of propaganda, as if propaganda is something countries never use on a daily basis. Out of all the countries in the world, America is at the forefront of propaganda psychology, and especially, making sure you don't see it as propaganda, but 'public relations'. This was studied in treating people as groups or herds, yeh, just like animals!
All you have to do to control people, is make them HATE something. And people will even use God to promote the importance of hate. Now how is that so different, from Terrorists?? Exactly the same tactics. Hate and fear are very closely associated, they are on the same branch. They are not on God's branch, or Jesus' vine. However the 'hate' referred to in the Bible, is a very different hate to what we consider as hate. However, people of course, use it how they want to hear it. And such things are used in propaganda.
In other words, the majority of Muslims won't kill us, but they seem to have no problem with the small portion of their brothers who will willingly chop our heads off.
