Essentially black history month is about patronising black Americans who are so insecure and narcissistic that they need to be told they are special every 5 minutes.
Can you imagine some guy in Nigeria being told that this a special month for his history, it probably confuses the fuck out of them. Why this month? Why only one month? Who the fuck are these people I've never heard of?
American culture is fundamentally narcissistic and this is just the black flavor of this, I'm not letting white people off the hook here, we do the same shit. Americans see the rest of the world through their racial lense and don't realise shit is a lot more complicated than that. There's no such thing as 'black history' in Africa. In fact even the concept of 'black people' is fairly new to them with the vast majority of people identifying far more with tribal and ethnic identities than racial ones. Black brotherhood is a myth dreamed up by delusional afrocentrists, the black version of the Italian Americans who would be laughed at in Italy for claiming to be natives.
Americans need to get over themselves and stop infecting the rest of the world with their egotism tbh.
