and there were similar "fringe" outbursts during the civil rights movement of the 60's. although i think think her response is pretty tame compare to other expressions of anger to oppression.

a movement doesn't hinge on one, two, or even multiple separate incidents (again, im not even sure this video even constitutes an 'incident'). it can affect the media narrative, yes. but i think some people that are going to denounce actions within this social justice movement were waiting to do so anyway.
