Islam can be reformed, and will be reformed, just like a puppy can be trained or a horse can be broken.
However, it won't happen just be offering islam tricks to sit up and beg, or roll over.
It's going to require means that are much more, shall we say, persuasive.
Regarding the persuasive means of reforming Islam , could that possibly include experiments in nuclear fusion over certain population centers in the Mid East?
Islam can be reformed, but won't be reformed till the Islamic upper echelon find it in their interest to reform.
Remember, Martin Luther didn't bring on the Reformation out of whole cloth. It was encouraged, protected, supported, defended, etc. by Germany rulers who were fed up with seeing riverlets of gold and silver flowing south, out of their lands and straight to Rome.
