Well, it really depends on the religions too, Judaism and Islamism don't boil down to don't be an asshole, they point out specifically to be an asshole (kill, steal, non-believers are animals,) then Christianity preaches the "truth" and tells you to have good virtues and other stuff like that.
idk really, but the Talmud says some shitty stuff about Jesus and non-Jews, so that kind of makes it bunk in the sense that the OT prophecy was fulfilled when God finally came down to Earth as Jesus to call out the tribe for being fuckers. And then Islamism? I don't know why they would refer to Jesus as just a prophet when he literally says he is God in the New Testament, I don't know how you could go from Jesus to Muhammad, whose virtues were violent and disgusting compared to what Jesus taught. I feel like if more Muslims read the New Testament, they might abandon their religion, but I don't know really.
