I've been thinking about this too. Hopefully I'll elaborate further when I have some more time, but I think the issue has as much to do with the definitions of "dignity" and "respect" as with sexist/racist/homophobe. Which is to say there are such things as attacks on one's fundamental humanity, but there too are attacks on a sort of lower-level dignity, a disrespect of the person but not her personhood: the question becomes more a question of courtesy than of morality, if that makes sense. Being ethical without giving in to the Cult of Nice.

Certainly anything which assumed an essentialist conception of what a racist, etc. would be would be problematic. I was responding to something someone else said, so I find it easy to believe that if I were phrasing the question while choosing my words carefully, I might be more specific as to which types of violations would count or not.

More later, maybe.
