Let’s not confuse people, things and ideas. Islam is an idea, the Koran is a thing and Muslims are people. I can accept your belief that Islam is devilish, but not the individual Muslims themselves.
Let me show you how I conclude that. There are about 2 billion Muslims worldwide. Assuming that 1/2 are too young or too old to be violent Jihadis that leaves 1 billion potential violent Muslims.
1% of 1 billion is 10 million jihadis. So 99.5% of all Muslims aren’t massively dangerous or even terrorists. That’s a lot of terrorism and it just isn’t happening at that scale worldwide.
Is Islam dangerous and destructive? I believe it is. As an idea Islam appears incompatible with liberty as understood in the West and particularly American Liberty. That said, moderating Islam is the only wise course to take. You do that by engaging Islamic countries in as free trade as possible and move them out of the middle-ages into the 21st century. Civilization is very civilizing.
