I’ve just been reading your responses and I think one point you might want to be careful with is “Human Nature” as if it’s a fixed static thing. Humans are capable of all manner of things in our natural form, but that does not automatically mean that those things are inherently good, healthy, or moral. According to just basic natural ability, and simple evolutionary strategy, every man should go around impregnating as many women as possible in order to propagate his DNA to the next generation. This was what our ancestors used to do, and it’s what many animals do in nature all the time, which is completely biologically feasible. However, as humans we are uniquely capable of rational thought, and we have the ability to rise above simple animal behavior, which is why the average person won’t go around killing each other’s children and taking each others mates. It’s an extreme example but I was hoping to maybe give you some idea of how the “Nature” talking point can be twisted to justify things that any normal person would see as absurd.
