The very, very insecure player base of Mordhau threw a fit, putting pressure on the neophyte developers to keep the game as white and male as a dry-erase board with a penis. Unable and/or unwilling to weather the backlash, the developers accidentally let slip that, while they were still intent on introducing more options, they were also considering introducing a toggle to let players switch off any of the diversity a player didn't want. Because nothing screams "good idea" like giving a bunch of bigots a button they can push to make all women and minorities disappear.
When confronted about this very discriminatory policy, Mordhau's semi-pro developers, who hadn't put any of their Kickstarter money into P.R. training, first outright denied the thing they had very publicly posted, then started backpedaling by claiming it was never really on the books. In July 2019, Triternion released an official statement denouncing their toxic players and promising that their future diversity upgrades would not be optional. As of the publication of this article, Mordhau players still can't play as minorities or women. At this point, it's fair to assume there aren't any left anyway.
