I mean, that's the whole purpose. I don't have a crystallised opinion on 3rd wave feminism but the 1st and 2nd were clearly necessary.
It's like saying the black panthers were bad because they were not fighting for white people's rights.
But overall I do agree, they needed some extra rights. However, the feminist movement now feels extraneous, as most of their rights have been achieved.
Like any good bureaucracy, IMO the organization exists to further promote its existence, goals be damned.
On the left, we don't use the word "minority" any longer, because the number of people in the group is largely immaterial in its marginalization.
Instead, we talk about "marginalized" groups which, regardless of their size, face systemic disadvantages peculiar to themselves. I consider the American white masses to be marginalized in ways made clear to me by Nancy Isenberg's "White Trash"[1], despite our numerical predominance (and complementary privileges).
So when one seeks to falsify Feminism, it doesn't strike me as remotely relevant to discuss the overall ratio of women:men. Women's marginalization is no less significant because it's widespread. To falsify Feminism, instead, one must adopt immutable definitions of "women" "men", I think.
I haven't personally teased apart my own socialized gender ontologies, however.
I'll just note that we're two decades into this one.
