I'm replying to this because I can't reply to ForHackernews's comment, but this really needs to be said: "patriarchy" is most certainly NOT "vague and ill-defined to the point of meaninglessness". To say that is to dismiss decades of feminist work. If you are genuinely curious about this, the book Feminism is for Everybody (by bell hooks) is a great, accessible introduction to feminism and the (admittedly esoteric and ivory-towery) language you need to talk about it.
