What are your sources of 40 murders? I only read of one murder of a non-Muslim, I did not read that one single Muslim has been murdered. As far as threats to mosques, apparently every Jewish synagogue is hiring security guards for their holy days (I don't think it's because of Christians or atheists possibly killing them). Doesn't that trouble you in the least? Or for some reason is it only threats to Arabs that bothers you?
Try again.
And do those other threats concern me? Absolutely.
But this thread's author claims American Muslims need to denounce this attack (they have) and
that the attacks against American Muslims have only been a few instances of verbal harassment (they have not.)
Start a thread on the threats to synagogues and I will denounce those attacks, too.
