Such Peaceful People
Yes, I'm sure that the entire Muslim world, apart from the small faction of extremists is VERY upset with those claiming responsibility for the atrocity in London.
The Council on American-Islamic Relations (CAIR) actually did condemn the bombing and they've been working to disassociate themselves from the terrorist element they have so clearly helped to foster in the past. Forgive me if I don't trust their motives. They want the Feds off their back so of course they're taking a moderate tone. Only time will tell.
Don't expect to see any wide-spread condemnation of this act from the Arab world, they're too busy just being peaceful Muslims.
