Muslims like to whine about how they're treated "badly" in the U.S., a frequent victim of Muslim doctrine. Fundamental doctrine in Islam requires the murder of infidels, especially Jews and Christians. It's not only stated in the Koran/Quran, but it's repeated. If only 10% of Muslims take their Koran seriously, that's 100,000,000 terrorists right there. So, yes, if you identify yourself as Muslim, it's reasonable to conclude there's a fair chance you're a potential terrorist. The burden of proof would seem to be on the Muslim himself, to demonstrate how he has rejected the Koran.

If one rejects the foundation of his religion, how can he legitimately call himself a member of that religion (e.g.)? Peace-loving (i.e., Koran-denying) Muslims would do well to distance themselves from the "Muslim" label altogether. Failing this, they stand the potential to take their scriptures seriously and start murdering us, and we're right to be wary.
