@msbellows actually yes. It sounds like he was just yelling "fuck you" at people way too much too, which isn't really okay in this setting either. It sounds like being in a crowd triggers him and he perhaps shouldn't be there, except maybe in a soundproof booth.
The racial abuse that he hurled at Michael B Jordan and Delroy Lindo was absolutely unacceptable (and doubly so that the BBC let it air).
