Have you spoken to practically any normal (i.e. not speaking on behalf of a government) citizen of almost any Arab or Muslim country today? Palestine is always on their mind.
If you want to have a meaningful dialogue you have to stick to the facts. Calling people murderers while not knowing anything much about your own, is not going to be very productive.
You're proving my point that some rulers are disconnected from the population when it comes to this issue. There is a strong unity among the Arab and Muslim populations for this issue.
