I'm of the belief that prostitution should be legalized and regulated, for the safety of everyone involved, for this very reason.in addition to being able to report missing sex workers without fear of endangering them, it would be good for them to be able to report clients who are violent (beyond agreed upon/consented to boundaries) because it would keep other sex workers safe AND they could be aware of escalating violence. with Francois again, when it came out that he was doing this, plenty of area sex workers were like "oh yeah that dude, fuck that guy, one time he strangled me so I never went with him again" but of course nobody reported it because they knew they wouldn't be taken seriously, AND they were putting themselves at risk of arrest.
As far as I'm concerned what happens between two consenting adults is their own business, who cares if jesus doesn't like it.
