Actually, Harlow is part of larger attempt to rebrand white men using black imagery, from the Logan brothers and their forays into boxing to Harlow and so on. You see it with over-promotion of Luka and damn near every great white hope in America, be it Brady or what not. The end goal is to make white men the face of all things good and masculine especially in areas where black men flourish while black men are portrayed as opposite. This is why 4cac and so on never seem to get shutdown despite their ties to terrorism - they play a large part in this in spreading memes in regards to this, due in part to that board being co-opted by st0rmfr0nt a few years ago. They've even gone far as ripping off memes that fetishsize black men and recast them in the light of white men, with "big white cock" (yep this i a thing they keep repeating now) and calling each other "king" (while simultaneously mocking black men by calling them "kangs"). Whites see thing in term of war and these fukkers see themselves embroiled in a culture war. The same shyt they used to glorify the nazis is the same play they re running to disparage black men. Companies are fine with this shyt because the same mindset that leads to them putting a white man as the face of a franchise because they see it as a safer investment, the same mindset that makes them do this with politics, is the same mindset they want to carry over to other forms of entertainment and culture. Something entirely homogenized, easily understandable (by them), and thus controllable. In the end, you get a system to further promote white supremacy and a means to make money off of it without any actual regard for black culture or black history as well a mean to diminish or denigrate black accomplishment.
In the end, memes and how they influence people are important.
