I'd say that natural things are vastly more likely to be immoral abominations on the basis that artificial things are created by people who have a moral compass and try to avoid immoral abominations, whereas natural things are created by Azathoth with the single goal of genetic fitness no matter how unspeakably cruel it is.

Yes that's why natural isn't the right word. What I meant by natural was "morally natural", but it was the wrong word to use.

I find it odd that consent wouldn't be assumed. You never hear people say that extramarital sex is bad on the assumption that they're talking about rape.

I was assuming consent in the sense that all parties are OK with it, but most people think sexual consent is impossible for children, so in that sense, consent can't be assumed.

I really should change it, tho. That version of consent is too full of holes and violations.
