Anyway, I have some objections to what 'third wave feminism' is generally used to mean--'sex-positive', strongly liberal/individualistic, endlessly finicky about its preferred language games, et cetera--but although my own views, at least in terms of my instincts and what I naturally gravitate towards, would probably strike a lot of people as 'first wave' throwbacks, I do think that there are also points worth celebrating in more recent feminism, like the somewhat more trenchant (if sometimes embarrassingly overcorrecting) discussion of race and the fact that femininity as a concept isn't as much of a bête noire as it used to be. I agree with Beatrice's point that the whole 'waves' model is basically a hash.
Ignoring that the "waves" concept is artificial for the moment, what exactly is it in your views that points towards "first wave" feminism and how does that contrast with what came afterwards? Is there some overall incompatibility or is it just a different emphasis on certain ideas and/or a rejection of later goals?
