I appreciate your comment but I think you make a mistake in treating "facts" as if fact-discourse is somehow different than political discourse. I don't mean 'there are no facts' or 'truth is what you make of it' or anything like that. Rather, the problem is one of selection. There are infinitely many facts. Selecting the facts that serve your purpose and omitting the ones that don't is not only a political choice, it's the quintessence of political discourse.

While I certainly agree (if I hear you correctly) that truth matters and there is such a thing as loving the truth for its own sake, I don't agree that public discourse can be divided in the way you posit. Quite the opposite.
