Get that Roli is his friend or whatever and it made him uncomfortable but the full thing is a madness. The Hitler was a good guy trying to get dirty Jews out of the country thing was insane, then Bryce full on launches into Holocaust denial.
Friend or family you have to call that out for what it is. Roli is looking off into the distance taking deep breathes and checking his phone knowing this is about to blow up, you gotta disavow if, call it out lest you become associated with it.
Any reasonable sport this results in Mitchell getting released and never being in the UFC again. You can't go full retard and bust out Hitler was a good guy with some good ideas, the holocaust was a myth they were work camps. If the UFC doesn't cut him this should blow up massively in the media that a ranked fighter is going anti jew, Hitler was misunderstood and the holocaust was made up.
