That is an incredibly lame explanation.
And a very bigoted one about Muslims.
No, it's right on target, and the "bigotry" is well-represented in the Koran, the Hadiths, sharia, the Saudi and Iranian religious police, and the Taliban.
"Bigoted" indeed.
The only "bigotry" is the presumption that "a stoneface look" from a Muslim male means that he's a terrorist.
Is that what you believe?
