Muslims try to disassociate Islam from all acts of terror, to win sympathy for themselves and Islam, especially with gullible people in countries where they are the minority. They say repeatedly that terrorists are not Muslims, or that an act of terror has nothing to do with Islam, knowing full well they support both the terrorist and the act of terrorism. The only intention is to convince non-Muslims that Islam is not part of the problem despite Islam being the actual cause  of it.
