I also addressed the issue of inbreeding by saying the following:
1) Consent from both parties.
In ideal circumstances, yes.
2) Protection is used to prevent reproduction.
Already addressed that one, we're talking with human beings here after all.
The fact that governing bodies around the world create laws doesn't make them objectively or morally correct.
Depends on the individual laws, and you know it. Unless of course you're perfectly fine with paedophiles and murder.
Prime example marijuana use in most of Asia can result in a death penalty meanwhile there is no link between marijuana having killed anyone due to its effects in comparison to a legal drug called 'alcohol' which can be severely negative to one's health and can lead to one's death.
The marijuana plant is so cheap and easy to cultivate, with uses medicinal and textile, it could easily hurt some greedy fucker's profit margins.
Alcohol is highly profitable with few uses outside of consuming, especially when for a long time in places like even London, gin was the cleanest thing to drink.
Not to mention it's controlled and regulated, and taxed, though not as much as tobacco.
Just because most governments on Earth believe marijuana is as harmful as heroin or arguing marijuana is a worse substance than alcohol, does not make these governing bodies correct in their argument.
Pretty much all governments have seen all the numerous studies proving marijuana to more beneficial than harmful.
I've already listed reasons why they'd be inclined to control how widespread its possession and use(s) are.
What I didn't mention was how much cheaper it is to cultivate than heroin, which has long been a massively profitable narcotic both legally and illegally for governments.
So again, what is objectively wrong with incest when both parties consent and reproduction is not involved?
If you'd read further onward from the post of mine you'd quoted, you'd already see my stance on that subject.
The problem is all the cases where both parties cannot consent, and reproduction is nothing to do with it but is all too often (proportionately) a byproduct i.e. intrafamilial sexual abuse, which is covered both by incest laws and child abuse and rape laws.
The fact that I'm even having to write these things shows that you're either being deliberately obtuse and responding as you are, purely for the sake of argument, or you're not as smart as your ego.
Now that's the last I'm saying on the subject with you, or anyone else for that matter.
My views are clear to see in the last few pages concerning actual incest, and that topic itself is so far off topic from the thread, that I won't be surprised if a staff member or moderator comes through and cleans up with warnings being handed out.
