The implicit attitude of this kind of writing is: ‘Can you believe these bozos are still acting like this?’ The tacit assumption is that we all take for granted a certain set of shared beliefs, and we should mock those few retrograde Neanderthals who do not agree with us. The tone is less urgent and more queenly. It contains the idea that feminism is cool, and that it will mock you like a cool and impressive girl at the lunch table if you are in violation of its principles. The idea is to make fun of your enemies, not preach at them. (This is not, I should add, a wholly new thing. There are historical iterations of this type of feminism in the work of Rebecca West, Mary McCarthy, and Germaine Greer, among others.)
