I honestly don't know what country you live in, but I've never ever encountered a "habit" or even a single instance of people writing "1f" on the sidewalk. Nor am I ignorant of the fact that gang rape exists (terrible but rare in Western society), war violence (terrible but not pervasive in Western society), domestic abuse (sadly common but not exclusive to men as perpetrators since I was actually abused by my mother who in turn was abused by HER mother).
Also I doubt that you actually know much about porn because if you go on sites like Pornhub you'll see that by NO MEANS is 90% of it produced by trafficked and abused women.
I also don't know where you get the idea that you somehow know "the cost of being in a relationship with MOST men" since you at most could have been in a relationship with 0.00000001% of all men in the entire world. Not exactly a great sample size to generalise half the planet.
It seems like you're generalising from your terrible life experiences and projecting them onto the entire world. Which is understandable, but not accurate. Your feelings may be valid but that doesn't mean the inferences you draw from those feelings are accurate.
