I don't know. Matter and anti-matter feels like physics or meta-physics, especially when it becomes linked to good/evil. Race is largely a social construction outside of a few physical features, but Earth-23 actually makes a case that race is essentialist because it can be "reversed". I can see why people think this is an Obama thing, since it has a sharp social point to make - especially in this latest iteration, Earth-23 is allegorical. That's part of what I paradoxically liked about Action
9, I suppose.
