i recently listened to an interview with germaine greer. what always strikes me about many feminists is how they have such a clear & distinct vision of what women should want, and what women should want seems curiously to dovetail with what they want. the main problem i have with left ideology as opposed to right ideology is the conceit by many leftists (though not all) that their own stance is value-free, and they are working objectively outside a “normative” framework. this gets back to the “isms” which people talk about all the time. is there really an objective measure for what these isms are, and if we don’t share enough values can we even talk intelligibly?
