The only reason why Muslims are not as a group completely terrible is because the vast majority choose to ignore the violent and brutal parts of the Quran. That's the good news.
The bad news is that the Quran can never be upgraded and some people think it's the literal word of God as told by the Prophet. There are always hardcore fundamentalists in every religion but Islam is by far the worst as they literally believe the Quran word for word, and those moron fundamentalists can thus be used as weapons by warmongers.
It's like, imagine that the world has several major and minor mobile phone OSes: Blackberry, iOS, Android, Windows, Symbian, Firefox OS, WebOS, etc. Now imagine that one of them (say, WebOS) can never legally (under the WebOS license) be upgraded from version 1.0 and that 1.0 was written 1400 years ago. That's Islam.
Sure, people can and have "forked" from the original 1.0, but there is a hardcore, militant group that believes that 1.0 should always remain "pure" and that any attempt to change it is a blasphemous "innovation" to be met with violence. So they attack anyone who tries to fork from 1.0, and also try to convert users from other operating systems.
Back to OP: If true, it's not a good thing to discriminate against Muslims in this way. It just stirs resentment and is not persuasive at getting people to drop WebOS. However,
http://www.reddit.com/r/exmuslim should be required reading for any would-be converts to Islam. Also, people who argue that "most Muslims don't REALLY believe ____" should read:
http://www.pewforum.org/2013/04/30/the-worlds-muslims-religion-politics-society-overview/ For instance, look at the % of Muslims polled who think that leaving Islam should be met with the death penalty. And the Pew poll didn't even survey the more hardcore places like Saudi Arabia, which would have even higher %.
For the record I believe most Muslims are good people, but DESPITE their cult (it is a cult of personality, let's be real here, the whole Mohammed-can-do-no-wrong-and-represents-the-word-of-God-and-his-Quran-is-the-infallible-and-literal-word-of-God thing is exactly like a cult), not BECAUSE of it. And even the "good" parts of the Islam are mostly stolen from the predecessor Abrahamic religions.
I find this behavior is normal among some circles. There is a general distrust of Muslims and absolute zero movement towards correcting those fears. We cry out about this behavior, but do little else.
We need to be more proactive at analyzing and addressing the root causes. We need to work with Muslims to build trust and place weight behind a peaceful coexistence. A balance against both the messaging (the nightly news casts of violence) and extremist groups.
Converts to Islam need to be drawn in by something other than violent ideas. Musims and Americans both need to look at violence and see a terrorist, not a Muslim. Otherwise it's all too common or easy for folks to see a head scarf and relate that to ISIS or any number of frightening groups out there.
