You missed the part of the argument where we need to care what group they belong to. How does that help anything?

Does it make their values any less "concurrent with their actions"?

Does it make it any more important that they specifically look in the mirror--not by virtue of their wealth or standing or anything, but simply by virtue of their race?

Or, in so recognizing the pattern (to the extent there is one--you didn't actually support that either), do we just make some members of the group feel set-upon as a group, even more than they already would feel by having their deeds judged? And thereby will they not be even more motivated to come up with rationalizations for why what they're doing was right all along?

So: why?
