porn turns women's bodies into a commodity to be bought and used at the behest of men... of course its inherently harmful to women
That's simply not true. It's a super outdated opinion that is not supported by fact.
In reality, women consume tons of porn - about 40% of it, last time I checked. So, your basic premise, that's its men exploiting women, is just wrong. Also, saying "of course" doesn't actually serve as evidence.
its not an opinion its a fact
women consuming porn also does not disregard its damage
there is such a thing as internalised misogyny
you have to ask yourself, what is the purpose of porn? the purpose of porn is to make women's bodies available for the sexual gratification of men (obviously i'm generalising since men are the main consumers of porn) at all times without those men having to negotiate with an autonomous woman to do so
this is the very definition of objectification which is a massive problem in our society
"The male and female subjects matched the photos similarly. They recognized right-side-up men better than upside-down men, suggesting that they saw the sexualized men as persons. On the contrary, the women in underwear weren't any harder to recognize when they appeared upside down, indicating that the sexy women were consistently identified as objects.
CONCLUSION: People objectify women in sexualized photos, but not men."
and objectification is the main driving force for various women's issues such as sexual violence since an attitude is cultivated in men where they feel entitled to women's bodies since they are just objects without agency
"You may be wondering why the sexual objectification of women has anything to do with violence if it doesn't explicitly depict violence itself. If nobody's suggesting overtly that rape or violence against women are a good idea, surely objectification can't be to blame? Well, not really. Research indicates that it doesn't just end with women being depicted as objects without humanity, needs or rights; it's about what they're objects for. The message, unfortunately, is often for gratification of dudes. And that approach can lead to some serious problems for women's safety."
this is all well understood and you need to come to terms with the real world consequences for women
