I have brought him up a few times already. But, remember, they're already wearing "Voluntary Members" by default. Josh might as well have called it a mark of shame since everyone knows what it means and who they're rubbing shoulders with over there. Of all the areas of the Kiwi Farms, BP is full of some of the most shameless and self-loathing. Mentioning an RSO who was also a proud 5-year RSO member isn't going to bother them at all.
Hilariously, though, it means all the BP holier-than-thou sentiments really aren't worth a snowball's life in hell. Obligatorily hating on an entire demographic for being born with a penis doesn't mean much when you're readily harboring pedophiles.
