Re: Zweihander RPG... I've got their books, read them, and I'm not seeing what other purport to see. Fox's politics are his own business until he shoves it down someone's throat. The closest I've seen in the books is a statement that gender is fluid... well, so is my taste in women. So what. I'm sure others have seen or heard things I have not.
Now: G&P on DriveThru RPG is allowing authors to publish stuff under the ZH banner using any published material any way they see fit... for a cut of the profits. 60/40 toward the author. I'm not seeing any parameters about socio-political themes demanded from the authors other than don't be a shit-ass blah blah blah, so theoretically I'm guessing one could publish an adventure about tall blond elves dressed in black gassing dwarves and shoving the bodies in ovens, and get away with it. Probably wouldn't sell many copies, but you could be damned sure it would get discussed.
