> It should be a matter of right.
I think that's a fine point to make, but I also think it's unlikely to be politically feasible, any time soon, in the US. You may have been perfectly capable of making this decision, but, in the most common case, most parents know that teenage brains driving almost adult bodies sometimes make really terrible decisions. And lots of us imagine we were much smarter than we actually were in adolescence. Moreover -- parents can be just as profoundly stupid.
I'd imagine a teenage Melanie Griffith would say she was perfectly capable of consenting to the very adult relationship she had with Don Johnson, and to which, I believe, her parents consented, as well. In retrospect, I'm not sure adult Melanie Griffith would feel the same. Or at the very least she may not allow her daughter to do the same.
Perhaps that's why we should willing to accept some guidance from things that at least can pretend to be objective -- science and journalism. Especially views critical of our priors and intuitions. And we definitely shouldn't seek to silence or de-platform anyone simply because they disagree.
Please -- vote the bastards out of office who don't take your problems seriously, but also please don't silence journalists for suggesting that there is more to this question than two simple American Left and Right narratives. Some of us need that kind of help to understand the world.
