The thing people don't understand about Neo Nazis (And groups with cult tactics in general) is that only the really STUPID ones will be upfront about the shit they believe like Jews controlling the world.
The SMART ones have enough self-control to hide that shit until they've bonded with their targets, people who feel lost and alone, and more often than not victims of intense ostraciztion, and after a sufficient period of time of like, weeks, THAT'S when they try to convince you that racial tolerance is bad, Feminists are evil, and being gay means you'll end up becoming a pedophile.
Someone with a particularly strong will or familiar with the patterns of grooming and cult bonding tactics may take that as a sign to get the fuck out, but others aren't so lucky.
So they show them the literally countless examples of SJW fucktardery, from BLM beating up a cripple screaming "FUCK WHITE PEOPLE AND FUCK TRUMP", to the Child Drag shows accusing anyone rightfully disgusted with them of being homophobic, and... basically anytime a Feminist says anything ever, and it causes their potential recruit to more easily buy into their narrative that "Nazis are the victims of a slander campaign uwu".
In short, the Nazis employ the worst kind of lie, one that has a grain of truth in it that makes it more believable, because the Left literally cannot stop blasting their foot off with a shotgun by alienating those not immediately buying into their cult tactics, and leaving them mentally vulnerable to Nazi predatory tactics.
And if shows like R&M had a better understanding of this and expressed it instead of "If you're even slightly more conservative than me that means you're hitler lmao" this problem wouldn't be nearly as bad.
