The problem isn't a few corrupt mullahs or princes, it's that the religion itself. It's basic text says it's ok to use force to convert, to enslave the infidel if they don't convert. The mullahs aren't corrupting the text, they are interpreting it pretty much as it was written.
It's been suggested that Islam needs a reformation, as the Christian church had one. However, the Christian reformation was a return to the text. The Islamic return-to-the-text Reform movement is Al-Queda and the associated mullahs, who want to remove the princes & leaders who have been cooperating with the Western infidels.
We can live with a corrupted, decadent Islam. It's the pure stuff that is poison.
Understand that I see Christianity full of some of the same vitriol. That someone can find a verse to justify anything they want to do...especially old testament.
Other than the actual words of Jesus himself, there is too much ugly stuff in the Bible. But again, that's my interpretation, and it's shadowed by bad experiences. (That keep being reinforced /sarc).
The same with Islam. Yes, it's bad, but logic says you can't wipe it out without killing 6 million people. I would like to believe a reformation would be encouraged first.
