Vox Day: What the Alt Right is.
Vox outlines 16 points detailing the core of the Alt Right. I did laugh at #12. Initially, I thought that there was a contradiction between points #4 and #15. There is none; they're carefully worded. So far, so good.
Later, in the comments (#90), Vox writes:
There is room in the Alt Right for Christians, pagans, agnostics, and atheists. There is no room for Islam, because Islam is a rival ideology as well as a religion. Therefore, the Alt Right does not believe in the freedom of all religions.
