> Given that feminism is the advocation of social and political equality twixt genders,
I'm afraid that isn't actually given.
That is your working definition, however, over the years there have been numerous "waves" of feminism and numerous often contradictory interpretations of what feminism and, even equality means.
Andrea Dworkin for example identified as a feminist, and is identified by some others as such, yet has written extensively about things that are far from simple equality. (Quite frankly, in some cases, anti male hate-speech)
Erin Pizzey, the founder of UK's first domestic violence shelter for women received bomb and death threats when she realised that equal protection from dv meant men should have shelters too. The self identified feminists who campaigned against her did not have the same definition of equality.
Even online dictionaries disagree with you on the meaning of feminism.
Google define feminism and you'll see that it says that it is the advocation of women's rights with respect to men.
Equality is in the definition, but what it leaves out is the acknoedgement that there are some conditions where women have significant advantage over men.
There are branches of (self proclaimed?) feminism that have different interpretations of that.
There are some branches that blame men for all the worlds woes.
Some that say a woman could never have as much privilege as a man.
The definition of feminism is so diluted as to be virtually meaningless without secondary descriptors.
What 'wave' or type of feminist? Radical? Radical trans exclusionary? Sex positive? Second wave? Third wave?
I'm sorry, I can't accept that "feminism means"
Why what about the campaign "feminism is simply the belief that women are people"?
Yet another definition.
Stienham through Paglia to Hanna Roisin (who recently declared men not equal but obsolete), feminism means a lot of things.
