SZA posted comments on a Instagram post from creator The Film Diva, calling out the misogynoir directed at Cynthia Erivo during both Wicked press tours.
Since Cynthia stepped in to help out Ariana when she was assaulted on the red carpet, Cynthia has been subjected to racist and sexist jokes and memes from Wicked fans.
Often Cynthia is depicted or shown as being hypermasculine or depicted in a mammie based stereotype.
