Also, OP, did you ignore or simply not see the lesbian human-half-orc interracial couple introduced at the literal beginning of WOTR?
Amusingly (and I am loving WotR, it's so far exactly what I would expect from a continued evolution from BG2) this isn't the first, or only subverted expectation.
The ranking leader is a female dragon. Your first 3 characters encountered.
Female Paladin - Black/PoC Female - Pictured as tough, capable. Female - Mutilated that guy, we all know it.
Then you get to the Hipster, couldn't get rid of him quick enough, followed by another Female character...
OK.
The we get out of the Dungeon and first thing we see?
