Very funny.
Since none of my nationality or religion has committed Mass Murder recently or ever, that is unlikely.
But if they did, I would not 'cop an attitude' if stopped, and I assure you if the Mass Murder involved fellow Americans, I would immediately offer to help catch the killers by whatever means are at my disposal.
I would not wait until my loyalty was questioned.
And since I have no inferiority complex, cultural or personal, screaming like a stuck pig is not an option.
I enjoy pork.
And when you did, like many American Moslem groups have already done, the creep squad here on FR would still want to beat the crap out of you.
Fortunately, the biggest bigots are the biggest wusses.
