This is going to be a fun one.
So here are the facts:
I commented on a news article about a mother and adult son charged with incest (and adultery as well for her.) This is what I said:
Someone responded to me and I replied before I realized my original comment was removed for being inappropriate. Then I added the edit when I saw.
The next day I discovered I'd been banned from that community for "pro-incest comments" and several others I don't think I've ever been in for rule 4 violations. The orignal post was removed.
You can see those here:
Site rule 4 is: Usernames or posts/comments containing transphobia, homophobia, sexism, racism, ableism, zionism, anti-veganism, or trivializing COVID. No self-described or obvious fascists, conservatives, or reactionaries.
My comments had none of those things. I'd even go so far as to say my banning was reactionary.
Now, I'm not defending incest, especially not for myself. My problem is with puritanical laws interfering with the private sex lives of people. In my original comment I stated that grooming was a separate issue and should be dealt with, but that there is nothing inherently wrong with incest. That is, enthusiastic consensual sex between capable adults.
I know someone will bring up the Hapsburgs, so yes, children of incest should be avoided.
If the power dynamic is clear (which includes parent-child cases like what OP was talking about, I'm in agreement with you there), then why should the law specifically care that the people involved are relatives, wouldn't more general laws about coercion, grooming, or abusing positions of authority be sufficient to make that a crime? (And if they aren't, shouldn't they be?)
If the power dynamic is not clear, like if both people involved are of similar age and there's not some other clear marker of who has power over the other like financial dependency or some kind of caretaker relationship (not "if there is no power dynamic", just if it's ambiguous enough to an outsider that there's a significant risk of an outsider like a judge or jury or cop getting the dynamic wrong), then doesn't having a specific law about incest risk punishing the wrong side a significant percentage of the time, or create a situation where a victim is afraid to come forward or can be threatened into more abuse, because they fear the penalty being applied to them as well if the law isn't convinced that they weren't the person with the power in their situation?
