I've asserted occasionally that post-modern moral theories (like the worthwhile parts of feminism) are consistent with empiricism. That is, they look at what as happened before and make predictions about will happen in the future.

That is often down-voted. I suspect that this is because taking feminism seriously would require people to re-think their methods of interacting with others, in a way that would be extremely challenging to their personal identities. That way leads to mindkilling (By the transitive property: The personal is political + Politics is the Mindkiller => The personal is the mindkiller).
