Could you elaborate a bit on your 'understanding of human nature'? I'm genuinely interested.
It's like anything that provides an easy dopamine hit: some people can get addicted, and the addiction can interfere with other activities. It can also serve as a substitute for forming meaningful sexual relationships with actual people.
None of this harm requires anyone to rape or sexually assault anyone else.
This, for me, takes us back to slavery. It was banned but hasn't stopped it.... but we still feel better as a society for having done so.
But outlawing slavery has, in fact, dramatically reduced how much of it there is in places where it's outlawed. The fact that we feel better for having done so is pretty irrelevant next to the fact that the ban actually reduced the amount of it.
But you are suggesting that in places where porn is banned, porn might still be a significant contributor to the prevalence of rape and sexual assault (hence the high rates in places where porn is banned). And that logically requires one of two things: either the ban isn't effective in even
reducing the amount of porn available, why bother, or that there's no dose/response curve for the effects of porn and that a little availability causes as much rapes as a lot of it. I don't find either explanation very plausible, but it doesn't matter, because in neither case would a ban accomplish any reduction in the number of rapes or sexual assaults. If you just want to feel smug for banning it even though a ban does nothing, I'm not interested in joining you.
Another more plausible interpretation is that porn is not in fact a significant driver of rape and sexual assault rates, and that other things matter far more. So if you're interested in reducing the rates of rape and sexual assault, focusing on those other factors is a better use of resources.
Here's a straightforward question (and I acknowledge it's inappropriateness outside this thread): Would you have sex knowing that a child could see and hear you?
I'm not willing to have sex with any third party, child or adult, observing.
