So i was over at my sisters yesterday and we we're debating the rights and wrongs of allowing pre-teens and teenagers free access to the internet, her standpoint being constant supervision and strict rules set in place where access is not allowed without consent, whereas i was arguing on a standpoint of education. this eventually bled into her bringing up a point about how she read a study(honestly couldn't even be bothered to look said study up when i got home and had wifi access) that stated that boys between the ages of 12-17 that watch pornography had begun to believe even into later in life that women are ideally supposed to look like buxom, big-breasted, bimbo's, and that this fact leads to teenage women and above feeling required to act dress and do absolutely stupid as fuck things(sending nudes, acting overly promiscuous etc), and that the consequences they face from said actions are unjust. i knew almost immediately as she said it that this was either a shitload of feminist propaganda lies, or the media attempting to yet again attack pornography as they like to do with video games and metal music almost every decade. Is there any studies i can show to prove to her that this is false? anything you guys know i can use to prove pornography isn't this huge evil demon she is making it out to be? any way i can prove to her that the "media" telling girls that this is how theyre supposed to be is an absolute crock of shit and if a girl wants to act promiscuous or post nudes no matter the age, that arguments such as "her feelings" or "how shes told to be viewed" are just plain excuses, and that if someone faces consequences, however radical they may be for their actions, that it is in fact just?

any help would be amazing, my sister for the longest time has been very neutral on the feminist issue, and this debate felt exactly like one with a feminist, so anything to help lead her away from that cult before she hops on the bandwagon would be infrickencredible.
