Similarly, MLK saw "the white moderate, who is more devoted to "order" than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice" as the biggest impediment to civil rights.

The bottom line is that being secure enough in your position in society to think you don't have to engage in politics, or that you can afford to vote your principles instead of tactically, is itself a form of privilege. Those sorts of privileged people think themselves neutral or uninvolved or maybe (in the case of professed leftists refusing to vote Dem as a protest) on their own third side, but the reality is that they are the right-wing authoritarians' greatest ally every single time.
