Literal neo-nazis have existed within the administration at relatively high levels (and likely still do, though they've gotten better about not outright bragging about it like some of those dipshits). People at even higher levels talk about conversations with literal neo-nazis, how they listen to their podcasts, etc. I'm not using this in the "I think everyone that has even remotely fascist tendencies is a neo-nazi" manner, I am using it in the "No these people are literally self described neo-nazis" manner.
The reality of the USA post WW2 is one that is full of plenty of shame. It still might be the most harmless empire there ever was, but that's a relative statement - the US has done * a lot* of harm. Perhaps a lot of good, too. Maybe even more good than harm. But almost all of that harm was unnecessary. But the past is not the future, and the present shows us marching to a darker and darker future.
Better to raise the alarm now and stop that descent rather than letting it continue.
