To stick my oar in for a minute, as I am wont to do, I didn’t find your comment offensive. That which is true should never be offensive, and those are some real metrics by which gender inequality can be measured.
However I didn’t get “humorous”. I thought it was intended to be serious, though I could interpret the intended message in several different ways—interpretations to which my responses could range anywhere from “total agreement” to “not even worth engaging”, so I decided to see where the discussion went before joining in anywhere.
I think if the humour was intended to arise from “this is not the type of list you expected”, you might be underestimating how frequently points about “gender inequalities which disadvantage males” are made in public discussions of anything related to gender equality.
I’m not criticizing your tone—I think tone-policing is rarely useful unless someone’s being an egregious dickhead—so I guess I’m just criticizing your comedy.
gjm already stated what he meant by gender equality quite clearly. I see no justification for putting words in his mouth.
