There are still good and reasonable definitions of fascism.

https://en.m.wikipedia.org/wiki/Ur-Fascism is famous, even if I think it overemphasizes some features peculiar to Italian Fascism circa WWII.

Like the other side calls everything communist or socialist? It’s all buzzwords people use

If they want to call everything fascist, well fascism you will have! Some may call it manifesting, almost like the left wants fascism just so they have something to degenerate about.
