You've never been to Manhattan apparently. Muslims from every racial group live here. My last cab driver was a white man from Algeria.I know this because he told me so.
Yes, but the overwhelming majority of the Muslim terrorists are Arab. Arabs are white, but not many are blue-eyed blonds. You can rule out black Muslims, because violent Muslims do not recognize black Muslims as true Muslims. Most of your terrorists will look like the run of the mill Arab. The big terrorist groups are very racist and only like to recruit people of certain races.
Also, the vast majority of bomb toting terrorists are 20-40 year old males. Very, very few are women. And almost none are older men. The young men are encouraged to fight, hence the 72 virgin nonsense and other such sexually related propaganda geared toward the young and dumb male. Also, the violence-driven extremist Islamic culture is a male dominated arena in which the male is king and women are dogs. And so, the male is the primary champion of this cause.
Let me suggest to you that 9-11 may have been prevented had racial profiling been invoked. There is a lot more involved in this than simply passing off every effort to secure our safety than to get overly-consumed with racism, which is not even close to the final objective of 99.99% of our enforcement officers.
Political correctness makes a man crazy.
