Because while there are aspects of feminism most women agree on, there are also aspects of feminism, or branches of feminism, that conflict with women’s beliefs in other areas.
For example, I see a lot of Germaine Greer quoting on Mumsnet about “women have no idea how much men hate them.” Most women don’t believe men, as a group, hate them. I don’t believe men, as a group, hate women. Feminists also sometimes have a dismissive attitude towards problems men have - who cares if men kill themselves at notably higher rates than women, women attempt suicide more! And a lot of the feminist “movers and shakers,” who tend to come from very educated and usually affluent backgrounds, have a tendency to do two things that are very off-putting.
One, they spend too much time on cultural trivia that’s not terribly important in the grand scheme of things. (Oh no, Greta Gerwig was nominated for the Best Adapted Screenplay Oscar, but not Best Director!) Two, they refuse to acknowledge that not every single man has a higher position in society than they do simple by virtue of being a man. When it comes to the ability to influence other people and shape laws, society, and education, who has more power? A working-class man who left school at sixteen, has never travelled more than fifty miles away from where he was born, and spends his time watching football with his friends when he’s not trying to budget around his child support payments? Or a feminist influencer with a degree from a top university, who has the money to donate to political causes and the time to go to marches and protests? For too many of the most influential feminists, the answer is “men have more power in society than women,” full stop.
Women also have a whole variety of opinions on the role of mothers, when abortion should and shouldn’t be legal, religion. Only some of those opinions seem to be permissible in feminism.
I think “internalized misogyny” is a term that’s overused. Sometimes women don’t hate other women, or themselves for being women - they’re insecure, or a particular issue has never affected them or anyone they know. And I’ve seen it used way too often as a tactic some women use to try to shame other women into shutting up.
I don’t know or care if I’m a feminist or not. I try to do what I think is the right thing, regardless of whatever label people want to slap on it.
