Dismissiveness is a way of disengaging from both the facts on the ground and the obligations those facts bring to bear on your life. As Michael Eric Dyson recently put it, "What is not good are ideals and rhetorics that don't have the possibility of changing the condition that you analyse. Otherwise, you're engaging in a form of rhetorical narcissism and ideological self-preoccupation that has no consequence on the material conditions of actually existing poor people."
There are really only two questions for activists: what do you want to achieve? And who do you want to be? And those two questions are deeply entwined. Every minute of every hour of every day you are making the world, just as you are making yourself, and you might as well do it with generosity and kindness and style.
And yeah, I know her calling them dismal is itself dismisslve. Good food for thought, in any case.
