For what will future generations condemn us?

Ask Kwame Anthony Appiah and Frank Pasquale.  Feel free to weigh in.  I wrote, in a comment to Frank's post, that "it was, for me, sad to note that industrial farming, and the cruelty-to-animals (that I agree) it involves, seemed to Appiah (and, I suspect, to most of us) more likely to result in downstream moral condemnation than, say, the fact that we identify and abort nearly all unborn children who have Down’s Syndrome."
