PP: Demanding dry water would be a logical contradiction, objectively-speaking, no matter who said it. Demanding that we talk about social issues without talking about social issues is the same way. Highlighting a contradiction doesn't have anything to do with 'tweaking' anything 'so that I'm right.' A contradiction is a contradiction.
model 29: In the micro sense, almost definitely. Word choice shows where focus is placed; you'd call somebody an asshole if you were attacking them for being an asshole, but you'd call them a slur if you were attacking them for whatever demographic you're slurring.
However, two caveats: 1) that's not the only way that an attack could be racially-motivated. If a black person surprises you and your first reaction is fight-or-flight as with many of the news stories that I posted, then that shows a fearful bias against black bodies. 2) There's also a macro element that needs to be emphasized, composed of society's reactions to said attacks, institutional punishments/lack thereof, and the precedent set by past incidents. That affects the atmosphere and power dynamics at work. White people have done some heinous shit and still been taken alive, whereas black people know what could happen if they mess with white people, so they'd have to be pushed pretty damn far to take that risk. Granted, it makes little difference to the victim in the moment, but these things affect chances of being victimized in the first place. It's a bigger-picture kind of thing: hate crimes against minorities set a shitty precedent for other people in that minority, whereas hate crimes against those in power are swiftly dealt with.
