If he is a Nazi, how did he get a security clearance to work at a Navy base?
Good question!
That’s the same question I had!
Most people who work on a military base have no security clearance. They do have to pass a standard criminal background check and child abuse clearance, and in general terms you have to know someone or get really lucky to get a job on a military base making more than minimum wage, but there's no social media investigation involved as far as I know.
Pay attention to this though. because all that is probably going to come down the pike. The social media probe is going to become normalized. If you ever cosplayed as a nazi for a youtube video, even if you did it to caricature nazis as terrible people, a screen shot still of you in a hitler mustache can and will be used against you if you fall afoul of the ruling junta if it suits their needs. Once they "other" all of those people, they'll start looking for their friends. It's all part of the game.
