Not everything is about politics.   

It does not seem to me that the women intended any mocking of black persons.   She did not wear the 'mask.' 0f black face we see in film.  I think she's being falsely accused of racism.   

Not denying racism remains a problem and I understand why a race accustomed to being mocked and assaulted would be overtly defensive.   I just think this became a mistake of 'friendly fire' that hit the wrong person.
