Maybe you should research into the Koran and Sharia and the Muslim concepts of jihad, taqiyya, and dhimmi.
Some labeled Christian do not accept the divinity of Christ, or reject/ignore certain parts of the Bible.
Same with Muslims in my experience. There are true believers (and they don’t agree with each other) and then there are Muslims of convenience, and cafeteria Muslims, much like some Christians.
In FR posts going back to 2001 I’ve related some of my Muslim experiences. But again, I don’t claim to be an expert on Muslims. (You can find FR posts where I’m not so modest about my experience with Mexican immigrants, which far exceed my Muslim experience.)
A month ago Muslim refugees from Clarkson GA were passing out Korans on the corner of Buford and Claremont NE of Atlanta. I watched them for an hour while on KFC wifi. Then I went out and got my Koran. I haven’t opened it yet. I have other priorities. In high school I read bits and pieces of the Koran and saw no reason to read it more.
