Whose Secretary are you, Minister?

This article irritated me. Obviously sexist abuse is wrong, but apart from Gillian Shepherd's anecdote, which clearly comes from some other age when she was first elected, is there anything actually sexist in there? Yes, there's abuse and banter, but is that all to be outlawed now? Were a female colleague to whisper to me, as I stood to make a maiden speech (God forbid) "You're flying low", I wouldn't take it as sexist. Irritating, maybe. Childish, maybe. But sexist!?
