Well the question really is why do we want to save it? What does it add to humanity or civilization?
Very little, obviously outweighed by the harms... I don't want to "save" Islam at all.
I think Islam need to be annihilated or at least diminished enough not to be a threat for a few decades.
Assuming you are talking about something non-violent, I agree that the long-term goal is the diminishing of Islam as well as all other forms of harmful superstition. Where we disagree is with how that is accomplished. I agree with e.g. Hirsi Ali that the best way to accomplish this is from within, i.e. similar to how the Catholic Church of medieval time was reformed.
Having studied it a bit more, I also think that those seeking to reform it are well intentioned but doomed to failure. There zero evidence that it can ever be reformed or will ever be reformed and part of that is the obstructive behavior of the left to even having rational discussion on the matter.
I think that the existence of actual reformers such that Majiid Nawaz is an example that there are Muslims who are promoting a more benign form of Islam; at the very least I think it should be tried and these efforts supported. But okay, let's accept that Hirsi Ali or Majiid Nawaz got it all wrong with the idea we should and can reform Islam. We still got to do something:
If not reform, how do you propose we annihilate or diminish Islam?
We can't fix Islam because people insist on wasting all the time debating if there is even a problem with it (when there clearly is). People like you do that bohm when your ideological conditioning to deny all issues kicks in.
How can I convince you that I believe the things I write again and again?
