I think that’s the only way Mod could come back is to say yes I was racist and I am sorry, it really is that simple. But she is too stubborn and embarrassed to openly admit it, she would rather face non stop criticism and not be held accountable. If she said she had been educating herself on the issues of racism and especially within her profession how deeply inappropriate her words were, then people might move on. She could have then used her platform to show how she has educated herself etc.
