WWE over the years have had a tonne of turmoil of all sorts of terrible behind the scenes behavior. Rape on both men and women, covering for wrestlers when they shouldn't (Jimmy Snuka) , promoted drug use , etc..... It's not like they've carried a squeaky clean image ever since Vince Jr took over. Even in the 80's it was in bad taste to have crap like Akeem and Saba Simba. Kamala I thought created the character before WWE so I don't think he would be lumped in.
I wouldn't say Vince is a racist himself, the guy only cares about money and doesn't care who gets it for him. I will say Vince has always shown to not have much class.
