Yes, this is correct. Only two things I would add: first, recognizing that those who sell sex are almost always victims does not mean we should have a positive attitude toward buyers of sex. Quite the opposite, in fact. I would actually argue that anyone who has ever paid a prostitute (of any gender) for sex should be excluded from a communist organization; OnlyFans is maybe a bit different, since it's all online and porn use is so accepted in our society, but I would certainly be very wary of anybody in a leadership position who was bought "services" on it. It's all a form of rent seeking, but with the rented commodity being an actual human being, and the "want" satisified being in no way neccesary to human life or human flourishing in the way that (say) housing is. So with the level of brutal exploitation in the industry, a principled Marxist has no reason to support it.
(For clarity, I don't think you were saying anything different, but in my experience it's good to make the point explicitly, because libs like to twist support for sex workers around into "visiting the red light district is AKSHUALLY a revolutionary act, and buying feet pics is just like reading Lenin!1!1!" We want to raise the productive forces and increase overall prosperity, so that everybody can work and support themselves, and nobody is forced to sell their body in order to put food on the table. In the meantime we can help sex workers through mutual aid, etc. Sex need never enter into the equation.)
The second thing is very minor, and feel completely free to disagree -- but I'm always bothered somewhat by the term "normalize," as it feels very idealistic. Things don't get "normalized" or accepted without some change in the underlying economic relations. So I don't think the normalization of sex work is good in and of itself; it's a symptom of some unhealthy cause, not people waking up one day and deciding to be less prudish. We're all a little prey to the liberal notion of social change, that it's precipitated by what Stefan Molyneux (remember him? what a bozo) called "magic individuals" who step up and "change the discourse." It might be good to avoid their language altogether.
Turning more overtly fascist, however, is absolutely not going to decrease the number of UwU's.
