Since you have a good relationship with them, I wonder, have you ever, or would you ever just suggest that they convert to Christianity? I can’t see why it makes sense for decent people who are Muslim by mere incidence of being born into it to not at some realize what a violent murder cult it actually is, and convert (if they can do so without putting their lives in jeopardy). Mohammed is the O.G. terrorist, so why do they follow him?
I don’t have a good relationship with all of them; rather, I know several Muslims that are really nice people. None of them seem to actively practice the religion; rather, they are Muslim in name only.
