This obsession with hypocrisy leads to a repugnant immorality. In an effort to defend members of their team, partisans end up defending the underlying behavior itself. After all, you can only be a hypocrite if you violate some principle you preach. If you ditch the principle, you can dodge the hypocrisy charge. We're seeing this happen in real time with some of Mr. Moore's defenders, just as we saw it with Mr. Clinton's in the 1990s.
