I'm not a huge fan of the religion, however, I know many that are and I don't hold it against them. They are not dangerous people.
A Muslim man does my yardwork. And here at work, I work with Muslims. Some are in senior management.
Islam is not all "one thing", as is Christianity, Hinduism or Buddhism. There are many schools of thought within it. As with many religions, there are fundamentalists factions and cults, and those are the ones who are dangerous. Those who commit terrorist acts are those who have been indoctrinated to do so by the same processes of indoctrination that are found in cults.
