If you read the strategies of the White Christian supremacists, they say not to make statements that others find outrageous but to gently push the envelope and slowly normalize their beliefs. Here, as I said, they are trying to rehabilitate Nazi symbology.
EDIT: In response to below, the problem with Nazism is people like me? Wow. I thought the problem was mass murder, brutal oppression, and an ideology that advocates it. But perhaps it's the poor, persecuted Neo-Nazis, who in another by-the-book rhetorical turn, try to look like victims.
EDIT2: dang: Sure, and let's keep the swastikas off HN. That and the hate speech are the real problems with very serious consequences. When you don't do anything about it, it would be irresponsible for me (or anyone) to stand by and quietly acquiesce. I know it's a hard problem, but burying our heads in the sand is what Facebook does. If you think my claims about what's happening are absurd, talk to someone you trust who knows these things: Certainly in 2018, we can't think propaganda in online forums is at all an absurd prospect.
EDIT3: Perhaps I could have found a cooler way to respond, but it's a pretty inflammatory thing and the commenter, supposedly versed in symbology, knew that it would be. Sorry if I caused any extra headache, but I don't regret pointing out the problem.
