There's probably something to that, but I've only really interacted with my cousins and her friends who all share the same instincts.
There was a screencap a while back arguing that women are incapable of making generalizations, for instance: "Asian men are shorter on average? I've known tall asian guys though!" or "I know a guy who is short and has a girlfriend, so it can't possibly be your height!" To my recollection it became a sort of "gotcha" for a while, a lot of people gloating about how retarded women were and such. It just seems dishonest, but at the same time I'm sure there are a lot of people who genuinely do hold those beliefs and so fuel the fire.
There seems to be this clash between factbound anecdote (case-by-case, as with women) and autism working to canvas initial priors (over-systemizing). There isn't really any safe angle to assume a middle ground, you just get called a poseur or a retard and you're left with nothing to talk about.
