I hope so. TBH, Rock's response was clearly taken aback, thrown off, and seemingly real -- though far less deterred than I would have been under the circumstances.

From a historical context, America sees a black man win an best actor Oscar as a black woman is nominated to the supreme court and then watches that black man assault another black man for making a joke. Jada of course perfectly capable of defending herself if she wanted to address it afterward. Will, of course, making it about him.... and "love".
