It is too much to hope for that the Muslims would become Christians. But I think becoming atheists is a major step in the right direction. A totally secular society such as the Soviet Union will fail, but if Muslims can use atheism to get out of the 7th century, so much the better. If they were the least bit rational, their people would have a better chance in life.
Sounds to me like an interest in rational thinking is on the rise, given the sprouting of young atheists. I can't imagine that the imams are going to allow this to go very far. Maybe, at this point, they'll just see it as a passing fad, like Americans do.
One reason why Islamic clerics try to drive out Christians from Muslim-majority areas is because they don't want Muslims who might be questioning Islam to have anyplace else to go, theologically.
