High School Girls Admit To Making False Sexual Assault Accusations Against A Male Student Because "The Just Don't Like Him"

The standard feminist position is: such false accusations are so rare that they can basically be discounted.
I'm more and more certain that this is false.
Here's one reason I'm dubious: the vast majority of things feminism has convinced me of in the past have been false. (Just one example: rape is not motivated by a desire for sex; it is a crime of violence.)
Feminism got a few big things right: men and women are of equal moral worth, they ought have equal political rights, and women have historically been oppressed/discriminated against on account of their sex. But mission creep has, IMO, killed feminism. It wants to be considered an authority on more and more things. And, like the rest of the PC left, feminism tends to adopt factual views because they're politically correct, not because they're the views most likely to be true. So I just don't rely on feminism anymore.
This is exactly the sort of question feminism is unusually unreliable with respect to.
