While I'm not defending this man standing around filming people there is zero evidence here that he is a Nazi. There are plenty of middle aged white guys with satanic tattoos who are definitely NOT Nazis. I know this because I'm a middle aged white guy with a satanic tattoo, and honestly I take offense that that seems to be the only thing you are using to qualify him as a Nazi
Maybe he's a Nazi, maybe he's not. The shitty flags on his car certainly don't help his case any, but there's no need to malign Baphomet by associating it with Nazi shitheads.
