That's certainly a coherent position, but I feel you're talking past me. To wit:
So now that I'm a member of an "unprivileged" viewpoint, I'm granted the privilege of determining what constitutes ignorance and privilege in other people--you granted it directly by asking me.
You misunderstand. I don't want you to make a determination because you are a member of the oppressed class; I know the answer, and if you had agreed with the hypothetical man's opinion I would have said that you are wrong as well. Discrimination can be documented objectively.
I was trying to illustrate that members of the oppressed class are always more acutely aware of their oppression than oppressors are, it's just natural. Likewise, with my farcical "shot in the dark"— of course it wasn't a shot in the dark, I was playing the odds. If we suppose that women are oppressed, then someone who doesn't believe women are oppressed is likely not a woman.
For what it's worth, I do agree with the statement that "We're moving towards equality pretty well, overall"— so much so that I wouldn't have put down too much money on ricefield being a dude, because I do actually know quite a few women who don't believe that there is meaningful gender inequality anymore. They are universally in my age group or younger, in high school or college, from middle-class families, and white.
They do in fact live in an environment where sexism is mostly about silly things. Now, I think that's awesome. But they're wrong.
Anyway, to take this all back around: The privileged tend not to recognize that they are privileged. It doesn't make you a bad person, it's just not something people notice. (It's still unclear to me if this is something you disagree with?)
If you want an analogy which doubles as an example: In a relationship, when the man thinks he and his partner share housework roughly equally, the woman tends to think that she is doing much more housework than the men. Statistically speaking, the woman in this case is objectively right; the man is likely doing much less than his share of the housework. He just doesn't realize it. If you ask me, it behooves a man not to rely on his perception of how much housework he is doing, because he knows that that perception is likely to be skewed. (Note that I'm not saying couples should necessarily share housework equally; these are men who want to, and think they are, but are not.)
So, likewise, the only thing I'm trying to say here is that if you find yourself thinking, "Hmm, that previously oppressed group seems pretty equal now" that your next thought should be "but then on the other hand I wouldn't expect to notice latent discrimination if it does exist, so maybe I should look into it a little bit closer." Not because you don't get the right to say things are equal if they are; just because they probably aren't.
