The problem isn’t that Islam is “pre-Enlightenment,” it’s that it’s anti-rational and anti-Christian.
“...its that its anti-rational and anti-Christian.”
So is socialist humanism, and all its evil. But those weirdos aren’t personally willing to die for it in order to kill others as far as I can tell. So I think those Islamists willing to kill for Islam must have something on top of that, something really bad.
