I’ve known Muslims in the UK and the US, the American ones seemed to be pretty docile, but I saw a lot of British ones were a lot more radicalized and prejudiced against Jews. I’d have to agree with the statement that most muslims aren’t terrorists but a LOT of them are or at the very least have terrorist sympathies or are receptive to Sharia.
I have fought against radical Islamists in Iraq and Afghanistan when I was in the US Army, so I know firsthand how barbaric some can be in their natural environment.
I’m Muslim, and very surprised at the other answers. My family and I, as well as many other Muslim friends/coworkers/acquaintances were absolutely horrified at not only 9/11, but all the other terrorist attacks as well.
It’s very sad that as a society we believe that Islam promotes or encourages terrorism. Terrorists are not true Muslims, but very misguided and disturbed people. Jihad itself is meant only to defend your religion in a time of crisis, NOT to kill innocent people, regardless of their faith, in the name of Islam. In fact, in the Quran it says that to kill one person is as if to kill all humankind.
To answer your question, I would say that a very small percentage of Muslims sympathize or commend terrorism.
