But who decides what's completely out of bounds? Like, sure, we find Nazi RPF really distasteful. What about serial killer RPF - is it okay when they were active long ago (and what's long ago? Ted Bunny or Jack the Ripper)? Some people find noncon fic distasteful. Some people think underage fic is a gateway to pedophilia. Some people find RPF about living people distasteful in general. You have to draw a line somewhere, and it's always kinda arbitrary.

I think RL Nazis should be punched in public, at best (I actually favour more radical approaches, but whatever), but I don't think people who ask for Nazis RPF shouldn't be allowed into Yuletide.
