Fortunately, nobody owns "the OSR". This goes for the right-wingers too, but especially for these entryist fucks, who largely came in with Zak and his crew around 2010-2011 (although they don't like to talk about this anymore).
What's galling is that in its infancy around 2004-2008, old-school gaming was a fairly conservative place, but it had considerable ideological diversity - people just didn't care much about your politics as long as you liked old D&D the proper way. Nobody would try to destroy you for being a lib, or homosexual, or whatever. These people, on the other hand, want to decide what you are allowed to believe, and who is allowed to exist in the online scene. Fuck no.
Gentrifiers, get out!
