When do other white Americans go to big rallies, or demonstrations, or press releases or anything whatsoever when some white guy in California shoots up a school?
Why do you demand that people who are not guilty of anything make some public act of penitence for those who are guilty?
Since you don't do it, why would you expect other Americans to do it?
Why should a Muslim who didn't do anything be "sorry" over something that some Muslim in Afghanistan does?
I dont' get this. I didn't see anybody demanding that we Catholics organize demonstrations when those stupid IRA trash blew up Protestants in Britain.
Some Muslims do go to rallies and even sponsor them. Even in Texas. Such as the one described in the link below.
Perhaps you haven't had the opportunity to make their acquaintance.
