Stevie, sexist patronizing is far from innocuous; it is horrifically damaging in the same way racism is damaging. Most people have an understanding that displays of racism are not o.k., but a lot people, have not gotten that far with their understanding of sexism. I grew up in the deep south where the best of folks could not see the harm in their language of racism, as they considered some of the terms endearing, and "normal".
We haven't gotten that far in our understanding of sexist language, expectations and behaviours. But you can easily see the damage when 8 yr. olds are sexually objectified, women are openly and publically called any number of degrading names. To make the difference more understandable, imagine if Don Imus had referred to Tony Dungey's winning team as a "nappy headed bucks". The public outrage would have been deafening. With the Rutgers women's bb team, the slander was taken as affront to their race, with little attention to the sexism.
That's the difference, and Barack Obama should, by his experience of racism, know better than to use language that belittles women. Sorry, if this has sounded like a lecture, but I expect better from a man that claims to want to unite the party.
