Seems reading comprehension isn't your strong suit. By definition, rape of any kind fails the "consenting adults" criterion pretty trivially. I draw the line exactly where I said I do, and the whole "the worst crimes I can think of justify the whole project of authoritarianism because it's simply a matter of degrees" line of reasoning is as puerile as it is unoriginal
Maybe I phrased it badly but I don't think it's insane that there are no governments that do that because there are obvious problems if they did. I guess you could go for full autonomy as long as the other people involved are not pissed off.
