I've called this the Ayn Rand fallacy before. According to rumor[1], Ayn Rand believed that she lived her entire life based upon the principles of rationality, therefore if you disagreed with her you were irrational. Ayn Rand didn't like beards or Mozart, so the men in her circle learned to shave and no one expressed a fondness for Mozart in fear of being deemed irrational. But condemning a bearded man for being irrational because Ayn Rand doesn't like beards says more about Ayn Rand than the bearded man.
Likewise, feminists believe their ideology is based upon the principle of not hating women, therefore disagreement with their ideology amounts to misogyny. But they aren't revealing their interlocutors as misogynists; they're revealing themselves as Ayn Rand.
[1] There is considerable controversy about the lengths to which Ayn Rand would go to condemn people for their irrationality due to personal disagreements, but treat this story as a parable; its literal truth is beside the point.
