MLK said it best, so I’ll just quote him directly:
I must confess that over the past few years I have been gravely disappointed with the white moderate. I have almost reached the regrettable conclusion that the Negro’s great stumbling block in his stride toward freedom is not the White Citizen’s Counciler or the Ku Klux Klanner, but 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; who constantly says: “I agree with you in the goal you seek, but I cannot agree with your methods of direct action”; who paternalistically believes he can set the timetable for another man’s freedom; who lives by a mythical concept of time and who constantly advises the Negro to wait for a “more convenient season.”
When moderates advocate for “kindness” or “civility”, they’re advocating for negative peace; the absence of tension. Vegans advocate for positive peace; the presence of justice. When activists advocate for positive peace, in the face of those who deny said justice, tensions rise and moderates fall back to this common trope.
