The horrifying irony of it all is that BattleTech has always been a very diverse game, lore-wise. There were a lot of different ethnicities on display, and both male and female characters doing a lot of shit both good and bad (hello, Katherine Steiner, Sharilar Mori and Natasha Kerensky, just to name a few...).
Sure, none of the Successor Houses are headed by a family of coal-black Africans but... it's probably for the best, considering how much every house has to play the role of asshole. It's easy to have the Kurita and Liao being utter bastards, no one cares about unflattering depictions of Asians these days no matter what the #stopasianhate crowd says. Imagine if House Khartoum, head of the Sudan Association, had to pull off shit like even the Davions do on occasion? Wars of aggression, underhanded tactics, sabotage, body doubles... we'd be hearing the twitter brigade's rage all the way out to Strana Mechty.
