Neither. I'm saying that people are responding to the words in his posts, rather than the underlying cause of those words. They're not saying, "Ugh, a mentally ill person, hate", they're saying "Wow, that's pretty offensive, hate".
In contrast, when the artwork of a schizophrenic gets posted (there's a particular one that pops up from time to time), people mostly respond with fascination.
But that's just the point. The words in question aren't any more charged with racialist intent than would be an equivalent work by the same person in a nonverbal medium, but one of those words in particular is linked to a reflex response called "offense", which apparently is so exceptional as to preclude any further analysis whatsoever even in people who don't fall within the group for whom the reflex-trigger word is a slur, and who therefore by definition cannot be insulted by its use.
I don't know, maybe it's just me. But when I see a lot of different people who've all apparently been trained to react identically and without thought or consideration to a given set of triggers, regardless of any context in which those triggers occur, it creeps me out just a little.
