So the approach is: When running straight into the wall doesn't work (i.e. ignoring the issues and simply calling everyone "stupid", "racist", etc.), we must try harder (we must fight them)! Okaaaayyyy...
John Stewart even made fun of this particular attack 6 years ago (http://www.cc.com/video-clips/m0pvy5/the-daily-show-with-jon...), and our principle easily extends to all the other accusations the Left thinks are still effective in their "fight".
