All the police and soldiers and all the people in their homes and stores and streets in the path of the protest were non-Muslim?
In any case, I'm not only refering to these riots in Kabul, but in every city/town Muslims have a riot in because someone said a non-Muslim insulted the Prophet or the Koran or Islam. Many thousands of innocents have died in recent years in vast regions of the world. To name a few: Pakistan, Indonesia, Nigeria, Sudan, Palestine, Iran, Maylasia, etc, etc. All Muslim countries. Almost all of the conflicts raging in the world are between Muslims on the one hand and any other religion on the other. That speaks loudly to me. Islamic people, not all, but enough to cause serious problems, cannot get along with non-Muslims.
