Many Syrian Kurds have.
Some are Christian, have been for some time.
Others are atheists. Product of PKK influence.
Some are still Muslim, but I don’t know one in Syria that is an Islamist.
Some like the Alevi’s have been secular concerning their neighbors for ages. That is why they were targeted by the Islamists. They got same treatment as the Armenians.
There was a community of Alevi’s in Efrin. Along with Ezidi and 2 Christian Churches.
You are obviously better informed in this matter than I.
All I know is what History teaches us, and the lesson to me is that Islam is an evil death cult.
There are Moslems, notably Dr. M. Zuhdi Jasser at The American Islamic Forum for Democracy, who are working diligently to reform Islam, and I wish them Godspeed in their endeavors.
Color me skeptical that Islam can be reformed away FRom its founding principles.
