No, I did not say that. I don't think he was sending that message deliberately. (As an aside, the message wasn't "don't talk to me.)
Oh, for real? Who blamed you for what?
You and _pius are clearly accusing me of racial insensitivity.
It may be non-racist, but it's still culturally tone-deaf.
I mean, I do think the "message" I claimed was being sent was stated overbroadly by me. But, for example, I definitely would not ever talk to a black person about their clothes if they were not wearing clothing I was familiar with, out of fear that they would be offended - even by a compliment. Even if I said something like, "That outfit looks really good on you," they'd like take my social awkwardness as a sign that I was somehow making fun of them (which I would never do). Or they'd consider me incapable of rendering a judgement about a style of fashion that I'm not familiar wth, and just be insulted.
Why should he make your distress a priority when you care none for his?
I never said that. In fact, if I didn't care about race relations and want them to be better, I wouldn't have commented in the first place. And I care about race relations because I care about people. I don't want anybody to be distressed.
needlessly distressful (racist, dehumanizing, othering, outgroup-reinforcing) things for the author
If you think the calculator incident was racist or dehumanizing, as described, then I can see why you would think I don't care about that guy's distress. But it was not racist or dehumanizing. It may have made the author feel like part of an "outgroup" as you say, but that was not intentional. At least as I recall the incident being described in the post. It was just some really naive person who made a mistake. I thought that was obvious from the description. And you may disagree with this, but if it was just a naive person who made a mistake about what the guy was wearing, it was not racism.
I'm not sure if I want to continue this discussion, but I will read any response and may or may not respond.
