White Americans voted for a black president twice. There's also still plenty of other black politicians who were voted in by the whites.
Look at literally every TV ad too, how many of them involve black people telling you to buy various shit? There's also countless black celebrities, musicians etc.
I'd wager a bigger percentage of white people enjoy watching the likes of Floyd or Mike Tyson, than say black people with Tyson Fury.
Racial tension and hatred is mostly driven by politicians and the media, most people aren't overly racist to a point where they'd allow their entertainment or political interests to be determined by skin colour, regardless of marketing.
If they're painting black people in a bad light because of their upbringing then thats on the marketers but they do it with everyone.
And whats the story on Floyd only fighting like that because he's black?
