Womens lib, like niggers lib, like faggots lib, like trannies lib is the ultimate conclusion of the Enlightenment ideals that our societies are built upon, at their fundament. At the point where you reject the notion that King and Noble have a divine or otherwise right to boss you around, make your decisions for you, and maybe kill you, then the conclusion that you too do not have a right to boss women/niggers/faggots and trannies around. Everyone is free to live their lives and pursue happiness the best way they see fit.
Inversely, once you start to reject womens lib, should you do so successfully and coerce women back into the kitchen and nursery against their will, it's only a matter of time before some fag is ordering you around by divine right, telling you where you can live and what you can do. And this is in fact the agenda actively and openly pursued by e.g. Fascists.
