I'm thinking on how David's comments are bringing perspectives to the
   posts here that otherwise are not well represented.
   I'm worried both that the comments could dominate the dialog, but also
   I'm worried that debate could be "won" against these comments, and then
   we wouldn't see them any more.
   These comments don't sound quite sensual to me, I don't really know,
   but that fact that someone is saying them here means that people are
   saying them elsewhere.  That means that people are believing them, and
   acting on them.
   Figuring out how to welcome and relate with the viewpoints behind these
   comments, could help protect edge communities like this one.
