An overgeneralization. Some comparisons are not valid. Some are. The checklist (posted in another thread) was pretty accurate, and we can see which of those were fulfilled by the Trump movement, and which weren't. It is untrue to say events and circumstances are the same, but -to borrow from a common saying- there is a lot of rhyming going on.

It is not wrong to be vigilant regarding such matters. "He who forgets history is destined to repeat it."

So far, rule of law is prevailing. Proud Boys are in prison. Indictments of higher-ups have been issued. At least some convictions will follow. The movement isn't dead, but people will be more careful before doing something stupid. Just ask FOX, who very quickly distanced themselves from "rigged voting machines".
