This is such a great observation! I hadn't thought of it in quite that way before, but you're right. Buffy's worldview isn't just divided into humans-good/demons-bad, it was also very much about the woman power-responsible/man power-irresponsible (or however else we'd label it).

The men around her are just as much active agents, even if they're not witches or Slayers. You don't have to be a superpower to have an effect on the world!
