Not being well-read in Dworkinism, I kind of look at it like the Matrix. One of those things where even if what she's saying is true, and we're living in a men-only world with virtually no opportunity for female advancement, then knowing that is only a big downer, has little effect upon the way we should live our lives (unless you go totally counterculture), so why even bother giving it any credence? Well, except trotting it out at parties to make yourself seem well-read.
