Admittedly it's not the same thing as Tourette's and definitely not nearly as severe as dropping the n-word in a public event celebrating an achievement by black people, but I go through something in a similar vein as an autistic person where I sometimes upset people by accident because I miss certain cues or am unaware of certain unspoken social rules. I feel bad and apologize when that happens because even if I didn't intend to hurt them, I still hurt them. I don't think that's self-hatred or "apologizing for my existence" as I've seen some people frame it. Davidson is apparently trying to get in touch with them to apologize, which seems entirely reasonable to me.

People talk about Davidson's right to exist in public as a person with Tourette's and he absolutely does have that right, which I don't think anyone here is disputing. What some people are overlooking is that being subjected to horrible racial slurs has a negative effect on black people's ability to exist in public. Accommodation has to be mutual.
