In contrast Islam was founded on a doctrine of submission by force. Either the force of allah's will or his follower's swords. Most Muslims may gravitate towards loving kindness and compassion, which is the true nature of mind, but there is no actual basis for that in Islamic doctrine. There is no way a Muslim could be forced to face his own evil deeds that would require him to admit to himself any "crisis of faith." There is nothing in the founder Muhammed or his original teachings that would reflect any fault for acts of anger and hatred towards outsiders.
Acts of loving kindness and compassion may find a space to exist in any given Muslim's mind but there is nothing fundamental to rest it on. As such it becomes optional in terms of core faith. As a result there can be no "Enlightenment" or reformation of Islam because there is nothing to go back to other than submission and forced conversion.
That means that one must view all of the "moderate" "peace loving" Muslims as "high-minded" Muslims that are not living lives "tested by faith." They're walking on shaky doctrinal ground and may step off when push comes to shove. It is anyone's guess whether a given Muslim will step onto more solid doctrinal ground (Muhammed being the primal exemplar) or renounce. What we do know is how high the stakes are for renouncing Islam.
The world is full of people that say they are this or that but really aren't so I can't hate all Muslims because of Islamo-fascists or Muhammed but ... Trust Muslims? You pays your money and you takes your chances.
I should have said "there is nothing fundamental to rest it on in Islam". There is most certainly something fundamental to rest thoughts of loving kindness and compassion on. The true nature of mind.
