Is the word lady a demeaning way to refer to non-men? I say it is, and note that out in the real world a non-man is a woman, unless she's (a) The Virgin Mary (usually used with Our) (b) some sort of British bluestocking or (c) a customer at a rural gas station: what can I getcha little lady?
Some of the more-bearded and less-enlightnened members of my commuinity continue to use the word and expressions like "lady's shiur" and "lady's section." I cringe. But if the non-men who read DovBear don't mind, I won't either.
