Dont know if the racism or complete lack of understanding human history is worse.
Orcs and the like are clearly based off Vandals(ya know the people whose appetite for mayhem was so prolific we now use it to describe mayhem; vandalism), Huns(ya know the people who dealt the death blow to the Roman Empire) etc. If anything its culturally appropriating the "abilities" of whites and ascribing them to blacks as being able to organize into such higher level entities.
Its becoming clear in the age of social media ALOT of people just want to be part of a community and have as much fame/power in said community. They dont give two shits about what the actual community is centered around or for they just want to be apart of the group.
Its why so much of everything turns to shit nowadays. Its not about being good stewards of xyz, its about sucking xyz dry for personal gain.
