"Chris Blakeley oh, I imagine most of the proud boys would gladly have a purity ball for their daughters..."
Somehow, it is against Facebook's Community Standards to talk about purity balls.
I'm guessing that this is because of Facebook's rules on mentioning "extremist" groups. This is also why even history pages on Facebook refer to Hitler as "An Austrian Painter" or "The Austrian Painter", even when mentioning him in a purely innocuous context.
