You guys are getting lost too much in domain-specific terms. At its core fascism is one thing:

The belief that a nation is like a living being and must do everything to protect itself as it is at that moment and try to grow, and that might makes right on a national scale. It's the belief that Darwinian principles of the survival of the fittest do not only apply to creatues, but also to nations and that this is also how the world should be.

Everything else is just the expression and logical conclusion of this belief.

And the nazis currently in germany specifically 100% subscribe to this. They do not want the national culture to be changed, they do not think other nations should be helped, etc. etc.

Even white supremacy is just a side effect of that. It comes from wanting the demography of one's country to remain unchanged.
