I don't think you're disagreeing with the article. True, I don't talk about power dynamics here, but I make the point that under liberalism, everyone has the right to express his or her ideas, even if those ideas are patently absurd, as religious ideas are bound to be for social reasons (as I explain).

But power differences aren't supposed to carry the day under liberalism. The question is just being pushed back a step: Why should those who are most intellectually in the wrong have the most power in society?

I talk about Foucault's cynicism elsewhere, and I just posted an article on whether postmodern dialectical explanations should undermine liberalism.
