Noticing this again, I feel I went much too easy in my other comment.

This science you cite is completely irrelevant to the dispute. My objection was not that emotional pain and physical pain are different, but that offense is not pain in any sense. That I admit emotional pain is real is quite obvious because I said that targeted racial slurs cause pain.

You cite a study to prove that emotional pain and physical pain are similar - a point that was never in contention. You then use a counterexample that simply assumes that offense is a form of emotional pain - assuming away the exact problem you are trying to address. My entire point is that the emotion of untargeted offense is distinct from the emotion of pain, which you haven't actually addressed.

I wouldn't typically re-comment on something like this, but the "Citing science for a tangentially related point, then following it with an unfounded assertion that is implicitly (but not actually) supported by said science," really, really bothers me, even if you did this unintentionally.
