But it's not just Nazis that are the problem. They're clearly in the minority. There's growing interest in garden variety fascism. Some of the hallmarks of that are nationalism, militarism, submission to authority, anti-intellectualism, fomenting fear of "the other" and outsiders. Umberto Eco has a list [1] that encapsulates and explains these. And, I'm sorry, but a lot of these describe the trajectory of the current Republican Party, especially under Trump's rule. (note: I think the GOP has largely abandoned what we would call "conservatism". Even though many of those left in the party might self-identify as conservative, they have veered into fascist ideology, they just won't admit it)

> An image of Packer inside the Capitol, whose sweatshirt bore the name of the Nazi concentration camp where about 1.1 million people were killed during World War II, has evoked shock and disbelief on social media. The bottom of his shirt stated, "Work brings freedom," which is the rough translation of the phrase "Arbeit macht frei" that was on the concentration camp's gates.[1]
Apparently the back read "Staff"[2]. While maybe not "literal" Nazis themselves, the people there seem perfectly happy to associate with and receive the support of literal Nazis.
