They lose the most status under current social changes and are therefore a vulnerable demographic for reactionary propaganda. And there’s plenty of reactionary propaganda for them to plug into and very little focused on them that runs counter to it, let alone gets promoted by social media companies. Reactionary forces are just doing good marketing, basically. It’s also not like everyone else is getting a great political education or has coherent beliefs in liberation or humanism, they just aren’t the status gaining group on which this propaganda works, they’re the groups scapegoated by reaction and when alienated will naturally oppose their bullies.
