As a 'privileged white person' myself, I take offense to your insinuation. Why should a person's skin color or status be a factor in whether they can legitimately fight for social justice?
Perhaps it has something to do with:-
Definition of
Partisan:
1. a firm adherent to a party, faction, cause, or person especially : one exhibiting
blind, prejudiced, and unreasoning allegiance.
Time and time again we have seen you defend or minimize the excesses of a certain 'privileged white person', yet for Warren you only have disdain. I wonder why?
