This is said about everything when the thing being talked about / protested is inconvenient. The funniest is when people say "music is not supposed to be political" when artists push back against something in particular.
Of course universities were political for a hundred years, and students were often very active.
Is the point you are trying to make that - because your college acted shitty during Vietnam - its cool if everyone acts shitty now? Not trying to be argumentative, really trying to understand the perspective of someone who survived the hell that apparently was Vietnam.
