Richard Spencer is a racist troll who purposely adopts his opponents' causes and pretends to back them in order to undermine them and get attention. That's what he did when he pretended to support "Zionism" (when he actually hates Israel & Jews). Folks should stop falling for it!
I wrote about this long-standing white supremacist trolling tactic way back in 2017, in the context of Spencer's pretense of support for Jews and Zionism. Every word of it still holds: https://www.tabletmag.com/sections/news/articles/richard-spencer-says-he-just-wants-white-zionism-heres-why-thats-malicious-nonsense https://twitter.com/Yair_Rosenberg/status/1297945767483781122
If you're trying to figure out whether a white supremacist or other bad faith bigot is trolling you or being genuine, there's an easy test: Is their statement consistent with the things they've said before and after?
