Yes, an interesting question. At what point, after multiple Islamic terrorist attacks and attempted attacks are we supposed to start disliking them, collectively. Never? This seems an impossibly high standard to ask everyman to uphold. Especially people wearing full hajib garb. That is, to me, a slap in the face to American dead. No, we can't go throwing bottles at people who offend us. But we do have freedom of speech. What about walking up to the lady and saying: "You know, I'm sure your a nice person but ever since 9/11 I just can't stand the sight of veiled women. It is forever tied in my mind, and the minds of many native born friends and co-workers with the evil suicide cult we are fighting world wide. If you like it here perhaps you could make an effort to fit in a little more and wear, oh jeans and a baseball cap or something. If that seems out of line maybe you and your family, strongly believing in Islam, should really move back to an Islamic country. You will probably be happier, I know I certainly will be. Good day."
Imagine being told this, or variations on it every time you go to the mall.
