This is incredibly misleading. Replace "overtly nodding" with explicitly disavowing: the post in question is literally called "Why I am not a white nationalist" [1]. And that's not "people have accused me of being a white nationalist, here's why I'm not", it's "here's why I don't believe this thing I find wrong." Oh, and here's what he has to say about racist blogs:
(The Internet is also home to many out-and-out racist blogs. Most are simply unreadable. But some are hosted by relatively capable writers, such as "The Uhuru Guru" or "Big Effer." On these racist blogs you'll find racial epithets, anti-Semitism (see why I am not an anti-Semite) and the like. Obviously, I cannot recommend any of these blogs, and nor will I link to them. However, if you are interested in the mind of the modern racist, Google will get you there.)
Does that sound like the writing of a racist to you?
