Practically speaking there's not much difference since there's a large amount of violent or extreme pornography which also teaches boys that directly or indirectly. It also teaches girls that it's "ok" cause they see it online.
There's many studies and organizations who publish warnings about violent pornography and young adults:
Dr Ruth Weir of City St George's, University of London, said extreme porn had been "normalised online" and was now "playing out in young people's relationships". [1]
Unless I'm missing somethiny, that article has no data that backs up Dr. Ruth Weir's claim.
It first posits that adult content has been normalized online, then cites unrelated statistics about abuse victims who had watched adult content. There's nothing that convincingly links that that first statement to the latter data.
A literature review of 19 academic papers, drawing on multiple methodologies since 2005, conducted
by the Government Equalities Office (GEO) to assess the relationship between pornography exposure
and negative behaviours towards women and girls found that pornography use had a statistically
significant association with attitudes supporting violence against women (with violent pornography
showing an even stronger association). [44] A meta-analysis of 9 studies found a significant association
between pornography use among adult men and attitudes supporting violence against women, such
as ‘rape myth acceptance’. [45] The association was found to be significantly stronger for violent
pornography than non-violent pornography. Other studies involving young adults, including Peter and
Valkenburg (2009) [46] and Hald et al. (2013), [47] have found that past pornography exposure among young
males is significantly associated with less egalitarian and more aggressive attitudes towards women.
This is particularly worrying when young people are being exposed to pornography.
