If you can't grasp what I'm saying and follow a logical argument, well, you can't.
Oh, come on.
And you have not pulled up anyone for pointing out these other descriptors and accused them of thinking that, for example, because they pointed out Ashkenazi nose as an inappropriate description, that means they think having an Ashkenazi nose is bad so they are anti-Semitic. Have you? Why not?
Innocenta has answered on her own behalf - but in fact I have raised that point, albeit less directly, and no one answered, except to say that it wasn't right to raise any physical characteristics at all where they weren't relevant. Now, that is a completely tenable position, but it does mean that to be consistent you should regard 'pretty' and 'freckled' and 'tall' as similar microaggressions. Do you? If you agree with Kimiko's analysis, do you accept that they are also appalling and extremely derogatory?
Or - do you in fact wince a little at the usage of 'butch' or 'brown' because you know, as we all do, that they have (often, perhaps overwhelmingly) been used in a context where they are indisputably slurs, and so you think that they have been associated with oppression for so long that it is in fact impossible to use them to mean only what they mean? That is, no one can ever use them neutrally (unless, perhaps, they explicitly say that they're neutral)? In which case yes, that is internalised prejudice at work - not making anyone a bad person, not making anyone less than well-meaning, but still prejudice - and the way we combat that is not never to say them, but absolutely to keep saying them in contexts where they are true and relevant, and to make sure no value judgement is attached. Prejudices - racism, sexism, homophobia - are the establishment of a false relationship between x (true characteristic) and y (bad thing). Regarding x as the thing never to be mentioned locates the source of the harm in entirely the wrong place, and reinforces the equation.
(I do not want to get into another piece of literary criticism, but I would point out that the butch girl with the moustache is presented, in context, as part of a discussion about uniform and forced gender conformity. She is held up as an image of unselfconscious, joyous freedom, contrasted with her older sisters: to accuse Clanchy of judging her for not being "sufficiently feminine" is spectacularly missing the point. But since we are talking about the terms themselves, and not the context, this is a digression.)
