Slavery: Not condoned, not condemned, just regulated. See here for details. But that’s a fair argument to make.

Incest: Only condoned in the early generations of humanity when it was necessary, directly condemned afterwards. I guess I can see how you’d be confused if you heard about it secondhand, but any familiarity with the cases in question ought to show this. Incest in and of itself (discounting other problems like rape and pedophilia it tends to coincide with) is a problem primarily because it leads to a higher incidence of genetic defects, and there were no genetic defects in the first batch of humans as God created them perfectly.

Murder: Obviously against the ten commandments. I don’t know what you’re talking about. Is it the death penalty? Are you trying to gish gallop me? I don’t mind answering your points, but I’d appreciate it if you be more specific so I don’t have to guess what you’re referring to in order to address it.

Divine right: In the strictest sense, that God gives authorities their right to rule, sure, but they’re not above accountability like divine right typically says. The Bible says to follow the laws of men only where they do not conflict with the laws of God.

Genocide: That’s a tricky one, where the Israelites were to wipe out the Canaanites. I don’t have a good answer for it. What I do know is that God’s judgment is righteous, and that this one case is not justification for genocides at human convenience (though non-Christians might interpret it that way, including but not limited to a certain state. I’m not defending them.)

Also, just so we’re clear, incest is gross, but it’s not fascist.
