I feel one of the biggest problems that Muslims often have is they fail to understand the age old rule - you come to my court, you play by my rules. Once Muslim numbers grow in America, expect to see more unrest when they don't get the changes they want. As I understand it, that is what has happened to Europe.
From what I have observed, the current of victim hood runs strong in Muslims. From the article:
Since 9/11, however, concern is rising among Muslim-Americans that they are becoming targets of bias and suspicion - by law enforcement as well as fellow citizens. It's a disquieting trend, say the young Muslims - one that might eventually help radicalism to grow.
Which no matter how you look at it is an attempt at justification and excuse making. Radicalism I can excuse. Terrorism there can, will and should be no excuse for.
