Is there any difference between (Neo-Nazism), (White Nationalist), and (MAGA Republicans)?

Nothing except the uniforms.

The following are just a few examples:

Rep. Marjorie Taylor Greene, Rep. Jim Jordan, Newsmax, Elmer Stewart Rhodes III, the Oath Keepers, the Proud Boys, Donald Trump, the Election Deniers, David Duke, Vladimir Putin, Mike Lindell, Rep. Matt Gaetz, One America News Network (OAN), Sean Hannity, Laura Ingraham, Mike Lindell, Michael Thomas Flynn, Rudy Giuliani, Tucker Carlson, QAnon, Steve Bannon. Governor Ron DeSantis, Kari Lake, and Sidney Katherine Powell.

It seems that (Fascism), (Trumpism), (Racism), (Neo-Nazism), and (MAGA-ism)
are all intertwined and they overlap each other.

Here with us, i.e. in the country of origin of Nazism, neo-Nazism stands for the resumption and spread of National Socialist ideas after the Second World War and the end of the Nazi dictatorship.
Representatives of neo-Nazism are called neo-Nazis; the term stands in contrast to "Altnazis" [old Nazis] (also Alt-PG, "old party comrade"), i.e. the bearers of National Socialist ideology who had already advocated it during National Socialist rule, the colloquially known as "Ewiggestrigen" [die hards].

In their basic convictions, neo-Nazis can be equated with the old Nazis.

Not even a Christian town filled with atheists and alternate white religions that include a light worshiping religion but are firm supporters of the execution of drug dealers and rapists. That never really happens. the federal and state not managing to put such laws into place. Very pro-white with white ethnic identities but seem to hate criminals, above all. The local alternate white religion, deny being Catholics every time someone calls them pagans. Perhaps higher atheist population locations result in more growth of alternate white religions. People sometimes see them moving into the forests in robes with hoods with torches during a full moon. The locals claim, their very kind and peaceful who follow gods and goddess of light. It was an atheist not the religious that beat up a Christian for spitting on their child goddess statue with the long dress that resulted in the farther decline of Christianity in 2 of those 3 counties, with a good portion having similar noses and jaws as the followers of light. Theory, spitting on their statue is the same as insulting their people and is seen as a threat to woman and children.
