Perhaps try reading the report linked in the third paragraph of the news article?

It's at: https://www.childrenscommissioner.gov.uk/resource/pornograph...

To quote from that report:

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.
