As we look back, it seems like willful blindness. The abandonment of the radical economic foundations of the women’s and civil-rights movements by the conflation of causes that came to be called political correctness successfully trained a generation of activists in the politics of image, not action. And if the space invaders marched into our schools and our communities unchallenged, it was at least partly because the political models in vogue at the time of the invasion left many of us ill-equipped to deal with issues that were more about ownership than representation. We were too busy analyzing the pictures being projected on the wall to notice that the wall itself had been sold.
