The Koran can never be revised. That would subject the contents as the absolute truths. The people who promote this religion are the people of the ME. The others are followers of their interpretations.
The other day I saw a video of a few muslims who want to reclaim their religion. I did not see any immans or Middle-Easterners in the group. Most Indo looking people.
No one wants to convert muslims or want to prove their beliefs are medieval. They put themselves into the frame. And beligerent about it.
