It is firstly most important to recognize the largest victim in this scenario: Jada Pinkett Smith. What happened to her last night is that, in a mostly white space, a Black woman was directly targeted by a person in a temporary position of power over her and made to feel lesser over an issue that not only is very personal for her, but one she cannot control. It's also an issue that, even if she could control it, inevitably plays into the sociopolitical ramifications of Black hair, especially Black women's hair, which is irrevocably tied to Black oppression. Look at the CROWN Act. Look at John Oliver's take on the matter. Hell, look at Rock's own documentary about the very subject. This is not a subject equivalent to the treatment of male pattern baldness in men, especially white men, and to treat it as such shows a telling ignorance of the matter. Pile on top of this all of the glaringly inappropriate comments about her relationship to her husband, which is all rooted in the realms of sexism and bias against those in open relationships, and what you have left at the end of it all is textbook misogynoir.
Ultimately, all Jada did last night was show up to support her husband in one of the most pivotal moments of his professional career, and she was not only attacked twice for it, but she has primarily been brought up only as a way to emasculate her husband. Jada was humiliated and then further dehumanized as a mere weapon, and that is unacceptable.
What is also unacceptable is the rampant ableism that has occurred in that thread. Of course the use of her alopecia in Chris Rock's set qualifies as this, but just as well, any psychological professional will tell you that a single moment of lost control or lack of inhibition is not any serious indicator or symptom of mental illness, or of more inappropriate terms such as being "unhinged" or "dangerous." All this kind of concern trolling and armchair diagnosis does is reinforce stereotypes that physical violence is strictly the realm of the mentally unwell, it upholds people to impossible and unrealistic standards, and it pushes away uncomfortable conversations about violence's role in the establishment and maintenance of modern society.
