It sounds like the guy is a hardcore D&D fan, which might shed some light on his thought processes. I ama fan of tabletop gaming, but you don't have to look far to see a whole ton of problematic and toxic sides to the hobby. Misogyny and racism were buried deep in the roots of the hobby, and it remains a hobby where large segments of the fanbase rabidly resist change. A decade ago, when I still heavily followed forums dedicated to D&D, there were still people regularly having discussions about whether or not male and female chatacters should have different stat bonuses and other similar topics. I have no doubt that there are still D&D websites where that is still a common subject of discussion.
I'm reminded of FATAL and its magic artifacts that turn you into ethnic stereotypes (adjusted further for greater white supremacy).
