It may be the case that neo-Nazis vote Republican, just as Communists vote Democrat. (In fact, open Communists are Democratic Party precinct chairmen now.)
Both Communists and Nazis can be "lesser evil" actors.
It is the case that mushhead Leftists have called Republican leaders 'fascists' at least since Richard Nixon. They probably call their mother a fascist when she makes them go to bed early.
The word 'fascist' is used in different ways by different people, some of these ways being in conflict with each other.
The most precise way to use the term is to use it to refer to movements that have stolen two things from the Communists: their 'social program', and their concept of a party-army, a quasi-military organization which looks like a normal political party, but which is also oriented towards the taking of power via extra-parliamentry means.
In addition to a pseudo-Leftist social program, fascists are extreme nationalists. So in some ways, they are similar to both the traditional Left and the traditional Right.
Fascism is as alien to American constitutional conservatism and libertarianism as communism is.
However, we can learn from the enemy, in this case from both communists and fascists. We need an organization which can defend liberty, on the streets if necessary. In cities where the progressives are in control, it is no longer safe for patriots to have public meetings or marches, since the police will be ordered to stand down and simply watch as we are attacked by AntiFa/BLM mobs. So we must be able to defend ourselves -- but in a sub-lethal way. (Bringing your guns to a demonstration is an idiotic move, playing straight into the hands of the enemy. People who advocate this probably ARE the enemy.)
This is something that needs to be discussed.
