You are completely right. There’s an entire ecosystem of right wing propaganda channels out there but most people get their news from their friends. It’s the key phenomenon behind influencer culture. And that’s how most of the damage is done.
If someone has one friend who is considered knowledgeable on current affairs and that one friend watches Fox, chances are that none of his associates will have an accurate understanding of any given topic. And that’s by design. The kind of tripe spread on fox news is inflammatory and salacious. The sort of noxious trash you’d share with friends in private conversation.
I realize this is what TikTok and facebook maximize: The friend effect. People learn from their friends. The kind of lies spread by right wing networks is magnified by social media and Russian bot farms.
For men you have a white power gang in almost every federal and state lockup. But because gangs like the Aryan Brotherhood are patriarchal institutions, women are not permitted to be full members. As such, when a female white supremacist ends up in jail, she is far less likely to find a group which shares the same political views.
