It's not so much that they are actual Nazis, it's just that MAGA and Nazi are the manifestation of the same ugly demographic slice that ALWAYS exists among humanity. Healthy societies keep that ugly slice of humanity under control in various ways, but now and then society weakens, and that ugly slice of humanity gets too much power, and because of who they are at their core, they cannot resist the opportunity to exploit and abuse that power.

It's not that MAGAs are really Nazis, it's that MAGAs and Nazis rose from the same source of bad humans. It's a nuance that many people don't understand.

Not hidden, but employed for weapon and rocket tech under the guise of national security. And that's not to mention the psychological torture we obtained/learned and experimented with in the CIA.
