I don’t think this is true at all. Most people are pretty ideological and think there are certain toxic ideas that need to be expunged from society. We don’t agree what those things are but ideology is a power struggle. Pure ideological libertarians are rare.

Nope. I think it’s something like a 27:1 ratio. I don’t believe in moral absolutism.

The specific focus on antisemitism in that first iteration was something that worked, something that struck a chord, and something that grew with wider support from Germans at large.

In any reuse of Nazi, as in central north american post Cold War Nazi 2.0's it's the ultra nationalism and "USA culture nationalism" that again comes as a core feature. There are strongly anti jewish factions, sure, but the strong binding "fear and hatred of outsiders" is well satisfied by brown people, immigrants, Latin X non english speakers, etc.

As noted by others, the deportations, the smash and grab storm trooper tactics, the Us v. them attitudes and camps on US soil and off all fit the patterns of behaviour set by original OG Nazi's. This time around jewish people by descent can clearly fit in and lead pan-USAism actions.

Post Y2K USofA identity isn't the same as 1930s German identity, but ultranationism is still kill the outsider.
