I believe what Krukowski means when he asserts to “the marginal-the rejected-the repressed” is that the power of marginalization comes from the people entirely.  Over time humans grasp on to something that will last for now but forget it later. By following this logic, he stating that their are also contradictions to his ideal idea of marginalization. He explains this at the very beginning of the episode in simple words, “even yesterday’s hits end up in the dollar bin eventually.” What we might consider marginal, changes over time and whatever catches on will have an effect.
