I'm not in America , so I don't have the whole picture on it, but I don't see much White Guy - Black Guy racism aimed at Floyd. A lot of people hate him, but it's because he's a prick basically. And maybe some of "the Brothers" love that because it's one in the eye for the White Guy. that's about as far as it goes racially.
Other people can't stand him, solely because of his style , but they should remember that Floyd has been around a long time, and he hasn't always been this "defence minded win on points" merchant.
Regardless of any of that, the guy warrants respect for what he has achieved whether you like him or not.
