Not everyone believes that only Muslims are terrorists - there were terrorists in Ireland for a long time. People like to believe in the concept of fear for a number of reasons, mostly the payoff is that they can manipulate others into giving them what they want by subscribing to an attitude of fear of terrorists. Then they are justified by hating those they fear and when humans hate something they can justify their reasons for taking what they want when asking for it doesn't work. Pointing fingers is no good either, though, Christianity, Judaism, Islam, and other religions ultimately teach humans to fear even though they espouse love as their principle - 'fear God, Allah, Jehovah' it's all the same. The Beloved is not to be feared or held separate from humanity; Beloved is one with all humanity - try to release your own fear that non-Muslims are thinking of you as a terrorist - some are, but not all. Peace.
