As a women growing up before "pc" ness I have heard a lot of stuff.
One that sticks with me, is my graduate school advisor giving me the advice as a woman; having a career, being married, having kids, that you can 1 well, 2 middling, and 3, well you should pick 2 of the three. I pointed out that there were already 2 graduate students with kids, and he pointed out they both had wives to take care of the kids.
I should have been pissed off, but I was more, that doesn't apply to me (because I had a hubby who worked part time). Sure enough even though I waited past graduate school until my job was more stable (just landed a big grant) to get pregnant, when my boss found out I was pregnant the crap hit the fan. So I think my former advisor was being well-meaning though it was harsh to hear at the time.
I didn't realize only 1 "race" could be racist. I guess I would think that woman's behavior was racist, because it is stereotyping. But yes it is different than institutional racism, which white guys do not get to experience.
Makes me wonder if she was responding to something specific on the screen, like a evil white guy?
