"For clarity, everybody on the planet called Jon Gruden "Chucky", and many, no doubt said this to his face, a reference to a murdering, psychopathic doll from the movie "Child's Play" ( https://www.imdb.com/title/tt0094862/?ref_=ttfc_fc_tt ). Surely, Jon Gruden would find no offense in any of those comments and I'm sure everybody who called him "Chucky" has been asked to resign from their job."
False Equivalency Argument.
Not remotely the same as making a racially disparaging comment. Particularly when you are public figure/commentator/coach in an industry that is majority Black in composition.
