You must certainly have read, watched, reports of differences in Muslim ideologies?   Not all Muslim teachers preach the same adherence to sharia law and you know that, or at least you should.     As far as American children of Muslim parents, many, like the generation of past immigrants, will assimilate American customs and laws in their first generation.

Here's one piece of sharia law that I looked at tonight.   Please notice that is has very different interpretation among the Muslim sects, let conflicts with interpretations viewed through a Western bias.     When you create a single negative stereotype, which you do, you dehumanize both Muslims and non-Muslims.   Those who make a single Positive stereotype of Muslims are also foolishly giving into their own bias as well.  Cultural bias alone creates ugly, sometime violent conflict from both Christians and Muslims.
