Still watching D&C's long-ass video and being reminded of a theory I thought up a while ago.
Do "hidden" alt-righters or white nationalists really exist? I don't think they do, at least not nearly to the extent that the Right Side of History types think they do. It seems to me that almost all of the people that actually believe that crap are pretty out, proud, and vocal about it, and that even applies to comics a la Vox Day and Jon Del Arroz and Tim Lim to a lesser extent. These people wear their political proclivities on their sleeves.
When evaluating whether Zack is an alt-righter or white nationalist, we can evaluate his choice in friends and women and come to the conclusion that he probably is not, but for me the even greater evidence is that he simply says that he is not. Find me an actual alt-righter who denies or used to deny being an alt-righter. (This could apply to just about any of these extremist/clique-ish political positions, come to think of it.)
