Why do so many Moslems go on a rampage when they are angry with the US ?

I have often seen on the news Moslem's going on a rampage,burning effigies of those they hate when they are offended, this I can understand,but what strikes me as nuts is that they often damage properties in their own countries and hurt their fellow citizens [e.g] car bombs. Cant they see the damage is being done to themselves and their actions are self destructive?
