What is your definition of feminism ?
Probably something to do with what the self-appointed feminist movement as it is exists says, as opposed to the general notion of non-prejudice and such.
Of course, when you define an abstract notion in terms of its manifestations, you're going to get contradictions, in that some feminists will say one thing, others will say another, so we are looking for the general trend.
While the ideas behind metal are great, and there are some fantastic metal bands still around, metal as a whole - both its creators and its followers - sucks massive cocks and should be disregarded. Thus, a new label like Hessian is needed which defines itself in terms of what the best metal represents, so as to mark distance from the 90%+ who degrade the genre.
If feminism is inherently a good thing, then it seems it now represents something totally different from what that good thing actually is, so perhaps a new term would need to be used now. Given the universal applicability of the idea which underlies feminism, it should probably be assimilated into a more all-encompassing movement which doesn't focus on any specific dichotomy.
Marxist tactics seem to only further the division between one group and another because of its constant focus on these differences (while ironically maintaining the illusory nature of these differences). It's not "self-actualisation for all!" it's "give this easily identifiable group we have designated the same status as this other group, for the meek shall inherit the earth!", which doesn't follow from any realistic principle.
