Why are you beating a dead horse around? You are never asking sincere questions and always have an ulterior motive to put 'Islam on trial'. It's pretty pathetic.
You should rephrase your thread as question about certain muslims rather than a question about Islam.
Islam clearly outlines that innocent people should not be killed. Yes the Muslims are suffering and struggling in Thailand and certain Muslims are resorting to emotion rather than knowledge in their struggles, in other words they would do some wrong in order to equate to some other wrong. Islam does not allow that but certain Muslims partake in desperation in such events.
Clearly Islam does not allow killing of innocent men, women and children. What certain individuals do is their own doing.
What about "Christian" and "Jewish" and "Atheist" Americans when they kill innoscent Muslims? Does Christianity, Judaism and Atheism go on trial? No, in fact.
Islam's position is clear on the matter, so there is no need to question it. It is not allowed to kill innocent people.
