We men objectify women in two major ways, one as sex objects and secondly as child carriers. By making women objects we dehumanise and rob them of agency. The correct (or healthier?) approach would be to recognise women as autonomous self determining agents that we need to harmonise with as opposed to control.
Thing is both sexes wether consciously or unconsciously lean into this, and on an individual level scores of women can benefit from playing the role of object (in either category), and it gets muddied when that is framed as a choice.
In terms of prostitution I really don’t know wether it is by definition a moral violation, but I think it certainly becomes one under the current paradigm where men hoard/generate the majority of resources. Until women claim their inherent liberty and are as a class at a disadvantage it must therefore be exploitative and therefore immoral.
When it comes to rape we can widen the parameters, but I fear you run the risk of diluting the pool so to speak and of say the example of sex with an intoxicated woman being by default a rape, then the same must follow when women sleep with intoxicated men, and yes I am aware that under (UK) law it is impossible for a woman to rape a man, but it would meet the bar for a sexual assault, and then we could very much end up in a tit for tat scenario.
I don’t know how useful this is, but where I am at with it and from observing the philosophical differences that emerge when this topic comes up is the sticking point is coming from does a woman have the capacity to say no to any individual man? So a prostitute may be forced into sleeping with men thanks to poverty, addiction etc etc, but she has (in theory) the right to refuse any individual man who stops his car, turns up at her flat etc. So yes she’s forced into it on a macro level but isn’t compelled to give into to any man who gives her the heebie jeebies. Of course the moment there is a coercive pimp, a punter who refuses to listen or she’s trafficked then yes I’d say it’s a rape then no question. I think this explains why so many people who want to see women better off can end up at loggerheads.
I sympathise as it’s a real uphill battle getting men to consider the wider landscape here as I’ve banged my head against that brick wall more times than I can count, and only rarely do I make any headway. I am broadly speaking liberally minded when it comes to sex, and prostitution, strip clubs, porn etc are all presented as part of this modern liberal sexy lifestyle we’re all supposed to buy into. I’m at a bit of a loss on how to shift men’s attitudes on this.
