Experts on what? There is no such thing, Islam has no real authoritative experts. Each splinter group as its beliefs, with nobody agreeing on anything. Each group interprets what they want, to suit their political ambitions.
How else would you get "experts" tell their flock, you go heaven and get 72 virgins as a reward from G-d, for murder. What do you think an unprovoked attack or ambush is, when your life is in no immediate danger? Then you go to a market, shopping mall, a street filled with pedestrians, a pizza restaurant, a library and simply murder the unsuspecting people.
Is this a religion of peace and tolerance? Really, I must be missing something? Go to the website "faithfreedom.org" to better understand the mindset.
