There is a long history of asking African-Americans to endure racism silently; it’s characterized as grace, as strength. Chappelle’s Connecticut audience, made up of largely young White males, demanded a shuck and jive. Men who seemed to have missed the fine satire of the Chappelle show demanded he do characters who, out of the context of the show look more like more racist tropes, than mockery of America’s belief in them.
When he expressed shock that he’d sat there and been yelled at for so long, people yelled they paid him. They felt paying for a show meant they could verbally harass him, direct him in any tone of voice, as though they’d bought him.
