> I want to be perfectly clear with you guys that many of the people who will be there are National Socialist and Ethnostate sort of groups. I don’t endorse them. In this case, the pursuit of preserving without shame white culture, our goals happen to align. I’ll be there regardless of the questionable company because saving history is more important than our differences. This is probably why they named the event “Unite the Right.”
> Speaking for myself only, I won't be punching right. We need to save civilization first, we can argue about the exact details later.
and from the comments:
> Exactly. Anything to the right of Elizabeth warren is already a nazi ready to gas six trillion Jews so might as well say fuck it. The enemies of my enemy are my friends

> The Daily Stormer [a neo-Nazi site] has been promoting the event heavily and it looks like they are going to bring a lot of young new cadres to the rally. Identity Evropa [a white-nationalist group] will be there as well as several Southern Nationalist groups. There will be no Alt-Lite co-rally, it will be just us, the proverbial and literal White Guard out there defending the statue of General Lee. This is a good development. They are quickly becoming irrelevant and losing their street presence as we continue to grow and take up space.

Describing the origin of the alt-right:
> On 4chan, the Jewish problem was analyzed by news junkies and history buffs, feminism was deconstructred by sexually frustrated young men, and race was considered based on the actual data on the issue. The rehabilitation of Adolf Hitler and the NSDAP largely took place on 4chan.
> This newly formulated Nazi ideology was then combined with the established troll culture, based on memes, hilarious images designed to transmit cultural concepts, and “lulz,” a term coined by the troll Jameth which defines the type of malicious humor associated with trolling.
The only way you can claim that they're not marching with neo-Nazis and promoting neo-Nazism is if you use a definition of alt-right that's different from how the alt-right define themselves. As far as I can tell, the term "alt-lite" was created specifically to disavow the small number of people who refused to stand with the neo-Nazis.
