Much of the confusion in this thread stems from different definitions of feminism.
Feminism can (in some people's eyes, but not mine) simply refer to ensuring legal equality between the sexes. This is largely achieved in the West, but not in Asia, Africa or the Middle-East (predominantly religious [largely but not exclusively Muslim] societies and developing states). However, that's simply being an advocate of human rights - legal humanism, liberalism, legal egalitarianism, etc. This isn't what most people think is distinctive about modern feminism.
Feminism can mean positive action - e.g. using the laws to enforce a perceived equality (e.g. enforcing company directorship quotas; rights over children, etc.). It can mean interfering with people's freedom of association, free choices, and so forth.
It can also mean trying to eradicate what are perceived to be feminine traits (due to the majority of females mannerisms, whether biologically or socially generated) - e.g. females being better at raising children, typical female interests (e.g. fashion, not football).
I think that only the first is the only essential, helpful and noble cause out of those three - providing equal opportunity and equality under the law, rather than trying to manipulate people's associations in a free society. From a personal perspective, rightly or wrongly, there is something deeply unattractive about a person who claims moral outrage all the time. Sure, I hate racists, sexists, etc, but I get on with my life and try to do the best I can to improve my lot with the freedoms I have rather than moan that other people are holding me back.
We live in a world where perceptions matter. Sure, it might not seem fair that females have to shave their armpits whereas guys do not have to care for themselves as much (though I suspect if I didn't shave my beard then I'd look homeless); but the fact is, most guys will think you're a disgusting mong if your don't shave. You have a right not to shave; but no right for society to think you're attractive. There's nothing 'unfair' about it, insofar as nobody is doing you an injustice, unless you think you have an inherent right to sexual attention.
You also have no right to crash into somebody's "men-only" party, but you have every right to think that the owner is an ******** (and I would agree). You even have a right to set up your own party and allow whomever you want into your home. Or your own company, and pay yourself and your colleagues whatever you want so long as you have the skills to run a profitable company.
I suspect the OP is a feminist to the extent that he agrees that females are humans and therefore entitled to the same human rights as men; but "feminism" often means much more than simply that, and a lot of the claims made by many feminists are at least reasonably contestable by fair-minded people who are not themselves sexist.
OP, since most people coudn't care less about these sorts of issues but are more interested in what DVD to buy from Asda tonight, I wouldn't stress too much.
