Thanks for this comment and thanks for reading. This is a weird form of OCD, in that usually people are worried about harm to themselves or those close to them. I'm worried about causing harm to people I don't even know. Thanks for sharing that you stressed about this also, now I don't feel so weird.

I just realized on posting this previous message that my fear of committing a microaggression is a form of scrupulosity and OCD. Now that I have a name for it maybe I can get a therapist to take me seriously.
