Pretty much or at least an organisation that adheres to all or the preponderance of the tenets of the ideology.

While I might suspect the Stormfronters would like to do that I don't know that they would, authoritarian fascists, sure, Nazi's not really.

Maybe it's because I like history and I've read a lot about WWII and the factors that led up to it but I'm careful with the world Nazi.

Been a race supremacist doesn't mean Nazi because logically a Black Panther would also be a Nazi then.

Been hard-right doesn't make you a Nazi because then the Republican party would be Nazi's.

Been pro-eugenics doesn't make you a Nazi because then the government of the UK, US and USSR where Nazi (in the early 20th century).

Been pro-nationalism doesn't make you a Nazi because then well half the governments on the planet would be Nazi's.

Been a race supremacist, hard right and pro-eugenics and nationalist just might.
