We (the staff) asked for a public statement of some sort, and he seemed open to that.
What are staff going to do if they don't like the answers? Quit? Strike?
But when they've taken a public position that implies they consider some employees to be less equal than others, yes.
Anything should of "I was wrong" implies he is not fit to lead a diverse organization.
The current state of things shows that he didn't feel like this needs to be addressed by himself.
