giving her the benefit of the doubt I had responded to "since you're jewish what do you know about the jewish mafia?" with an explanation of the Purple Gang and Meyer Lansky and the absorption of the mafia into the national security state, and she comes back at me with that.
This came after two days of me explaining historical materialism to her. I think there's a lesson to be learned here about white people
Tell her "We invented those stories to take blame for it, so you whites wouldn't feel so guilty all the time".
See if it makes her brain stall out to consider that getting people to talk about how "Jews control the world" is a secret Jewish plot.
