"Dave's not queer, man!"
Yeah sorry David, D&D has never been like that. Hell look at the original Elven gods. One could be anything he wished. D&D today caters to your crowd by destroying everything that made the races interesting. You may as well just fight robots.
As for an open white supremacist? I assume he's talking about RPG Pundit, who is Latino and is also opposed to white supremacists.
Seriously, being an open white supremacist is one of the few things that can get you banned from Pundit's forum.
It's a preset narrative that RPG.net and Onyx Path have.I really wonder where he's getting that, outside of just making it up.
