I had an argument about feminism today. There wasn't anything new or exciting about it -- I walked into a classroom at the tail-end of an argument between a professor and a student about whether that professor should, when talking about feminism, give equal time to the kinds of oppression men face. The guy's argument was that, since men deal with systematic problems too, they deserve equal attention in any argument for justice. His two pieces of evidence for men's oppression were the higher suicide rate and "Having all that extra power is a lot of responsibility."
His criticism of my argument was that I was failing to define sexism in explicit, straightforward terms. The meat of my argument was that sexism is a problem of such great complexity that it's impossible to reduce it into straightforward terms in a satisfying way.
It was very frustrating.
