Essentially that is part the 'male sedation hypothesis'.
Due to the amount of incels or men who aren't really in relationships or even work these days, they should be causing significant social unrest as they have nothing to lose and try and overthrow the current social structure. In reality we hardly see any real violence or trouble from incels other than the odd angry rant on social media and the idea is that things like porn, video games and social media take care of the base needs just enough to stop the angry from boiling over and causing real trouble.
