Fascism isn't really a form of government though, it's a political ideology and aesthetics that we see echoed through different regimes. You can be a democracy on paper while in practice being a single party corporate oligarchy with a cult of personality surrounding the head of state.

Ur-Fascism describes the ideology of MAGA exactly. Clearly there's some apprehension admitting this, it's a strong-man political ideology that has evolved many times organically throughout history. It doesn't necessarily imply that the regime is bad or evil or anything but the problem ends up being that the term exists because governments that adopt this ideology end up converging on the same unsavory behaviors despite any initial differences. That convergence is I think what a lot of Americans are afraid of because we're already doing most of them.
