These corny mother fuckers always about that Egyptian shit when our ancestors were from west Africa
it never ceases to be comedy how they pump their chest with the idea of black pride while at the same time unironically throwing their ancestors to the bushes by fetishing a single culture and country that our victims of the diaspora didn't even hail from.

...or when they go and claim European history up to late medieval era 
What I love is that, no matter what the person's background his and whatever the site they decide to engage on with their schtick, they trot out the same ridiculous copy-paste about Diop, paintings and king's surnames.
Explain this more. I haven't seen that.
There's a whole movement of people on the Internet claiming to be "afrocentrists", based (maybe very loosely) on works by Cheikh Anta Diop. They'll claim the egyptian heritage but will also try to convince you that up to the late medieval era, Europe ruling class were really all Black people. "Blue blood" is in fact black blood. Their evidence generally goes down of linking paintings with a black guy in it, painting of kings and nobles where the skin color is ever so slighty dark or where we are meant to see "obviously negroid features" (Yeah, some actually do talk and think like that), overreaching in interpreting surnames, etc...
This is a good example : the most vocal believers will generally bombard you with dozens of such filmsy cases. At one point, they claim, the black rulers of Europe were overthrown by the whites (or "leucoderms") who then proceded on inventing slavery and evil. Expect shenanigans about how Olmecs (or any given random past population) were black. Don't expect for any actual scientific relevance pertinent to migrations of the past. If you feel you are ready and have time to waste, enter the
Black MatrixWriting history from an African perspective is of course a valuable and meaningful course, but this particular brand of "Afrocentrism" is really just a naked fantasy of racial supremacism.
MAAT will set you free, brother.
