He was arguing that whites should support a separate black nation in Louisiana, Georgia, Alabama, Mississippi and a few other areas. I said I was against it.

Sexism has persisted for over 2,000 years, but it has been so completely saturated by the political-economic processes of modern capitalism as to be very different from 2,000 years ago. There are some similarities, there are certainly some powerful vestiges, etc., but these are not rooted in some Jungian collective male consciousness that all males are born with.

This does trivialize the issue. The most profound forces are not some essential, inherent tie that binds members of those groups together. To the extent that we find temporary comfort in escapist islands, we undermine our struggle to defeat oppression. We all have weaknesses and should not beat up on ourselves or our allies for having weaknesses. Our being, our identity comes from our actions.
