Usually, if a figure of any degree of prominence accuses an institution of racism, that institution is going to do a whole lot of hedging.
It doesn’t matter what the particulars are. In its public statement, the institution will acknowledge the trauma the individual must feel — and how generational trauma affects all people of [insert minority group here]. They’re conducting a full investigation. They can’t speak on the specifics due to privacy concerns/ongoing legal proceedings/etc., but they take the accusations Very Seriously™.
Thus, when former first lady Michelle Obama’s brother and his wife sue a private school claiming the disenrollment of their children was “retaliation” for their bringing up concerns of racial bias and the school straight-up calls it baloney and states there was “persistently disrespectful, bullying, or harassing behavior directed at our devoted and hardworking teachers and administrators,” you know things are really bad.
