"Never interfere with your enemy when he is making a mistake", a maxim attributed to Napoleon, works well for what I'll label as the Alt-Right here, defining us as those who's response to being called racist is "We Don't Care" instead of automatic surrender.

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".
