I no longer believe that's possible.
Edit: Just to make this explicit: I don't have any eccentric or unorthodox views about the differences between "races." I haven't advanced any such views here, nor do I hold them privately. tptacek's implication, of course -- and this happens in every single one of these conversations -- is that I'm concealing some detestable opinion about race. That's why there's always this persistent pleading to clarify what you actually believe. I've stated quite clearly what it is that I believe. No more or less. If I haven't been clear, then we'll just have to attribute that to my failings as a communicator and call it a day.
