Look at it again. It's referring to a person that the writer of the post doesn't know from Adam saying "that comment's worth fucking you for". She objects, rightly. A sexist circlejerk ensues and all the sexists rally to support each other. It's not referring to the people who would not say such a thing, but the people who rally to defend the ones who do, of which that's something a bit too common in our society as it is.
