Well, I would certainly expect the 'attempt at informal logic is ... laughable'. I wrote it to be ridiculous.

I guess I shouldn't have bothered with the reply, as it appears to have triggered a pissing contest over Logic technicalities. Or perhaps you think a dispute on mechanics is going to erase the problems inherent in the idea that selective power assignments to individual agents based on uncontrolled genetic factors is required to determine whether or not an act of sexism is verifiable sexism.

The efforts to redefine sexism/racism/etc as power-dependent are philosophically problematic. I'm rather uncertain we'd get anywhere on the issue.
