"'half' inherently racist
imho it is vice versa. plz let me explain:
humans technically don't have races, the differences are way to small - we just call them races which is inherently racist. Calling a human 'half - whatever' IS inherently raacist then. Obviously.

Removing 'half' from a game where races actually exist is a bit racist tho because ppl. are taking our own human rules and problems and apply them into the games world. 'half' in DnD ist just a fact. Nothing more.
