"Whatever women must do they must do twice as well as men to be thought half as good. Luckily this is not difficult." -- Charlotte Whitton (1896 – 1975), Canadian feminist and Mayor of Ottawa.
A sociology professor once asked me which person I would hire as a mechanic if I had a man and a woman, both equally qualified, apply for the position. Initially I replied that I'd hire both and keep the one who did best. After a moment I amended my answer, saying I'd hire the woman because when the guys saw her kicking butt they would start working a lot harder.
