Since we're bringing up Yuri Bezmenov, I present Bella Dodd. Unfortunately there isn't an easy interview to watch because but you can try to listen to this poo butt recording, read her autobiography, or read either of her two testimonies to the House UnAmerican Activities Committee confessing her work for the Communist Party USA.
Basically she was an OG subvertee, a catholic college student turned agnostic socialist, then professor, then CPUSA lackey and Teachers' Union influencer, and eventually leader in the CPUSA. It's the exact story of Communist indoctrination and subversion that you aren't supposed to know about and it sounds shockingly similar to how things go down nowadays. She believed she was joining up with the only people who even cared to fight fascism (post WWII).
