We have literal, open and proud Nazis who wear swastikas, text their mom Hitler pics, and drive their cars into crowds. The concern is warranted.

It's a strange thing about today: many people want it to be some other time and place and try hard to pretend that it is. It's kind of understandable that much of this centers on WW2, given that a lot of the patriotic mythos in the US comes from that time. Maybe because it's the last time the USA won a major war and got to feel heroic, write history, etc.
