This is how commies think .If you think of culture and history as a "product" suddenly it all makes sense. The communists think "your culture and history is good" and " your culture and history is impressive" so "that's unfair", it needs to be given to another race whose culture and history is "not so impressive".
Suddenly it makes sense why they culturally appropriate European and Asian cultures and history and insist on black washing it . They want to steal the culture and history of Europeans and Asians and give it to another race whom they consider their culture and history to be more lacking, to make things more "equal"
Well other than the fact that they also want our countries to accept black immigrants and they want to genocide us , and blackwashing our history is a way to do that
The unspoken idea underlying with this is, just like DEI and affirmative action, that Blacks are inferior and need extra help just to compete.
