@Kyle, it is unlikely that its true, I trust the US authorities to raise a red flag if it truly were the case. If anything, it is more likely that that particular age group of males will be subject to more scrutiny and rigorous screening.
@Cal, just to correct you a little bit, Muslim is not a religion, Islam is. Muslims are those who follow the religion of Islam, just like Christians are those who follow the religion of Christianity.
There is no arguing that these extremists need to be eradicated, but it is important to make the distinction between extremists and Muslims. With the former, you're talking about eradicating a few thousand (who desperately deserve it), while the latter, you're talking roughly 1.7 Billion (many of whom are also the victims of extremists).
