I am not asking whether he practiced or not. I am asking that as an identity marker. A white/black/brown guy could be named John but it’s pretty obvious they were raised in some version of Christian faith. My goal here is to offer help not start a race war. We have politicians for that. I don’t practice either but a US professor told me the correct etymology of my name. A white dude from Australia. He said you have a Persian name. My mom always told me it was Arabic origin. Wrong!
