This only works when you redefine fascism to mean, "support for any single policy to the right of Mikhail Bakunin". Creating an overly and inappropriately broad definition for fascism that doesn't align with any common definition, and then labeling everything you don't like as fascist harms your cause more than it helps. Saying--for instance--that people who don't want homeless encampments near their business are fascists makes other people see you as unreasonable and not worth engaging with. If you want to turn people off, then that's a fantastic way to do it.
people refusing to vote letting the fascists win does not in fact mean the other party is fascist as well.
I can't even parse your meaning here. MAGA Republicans are 100% supporting fascist policies. Establishment Dems support some aspects of fascism, but are not fascist. Likewise, traditional/principled Republicans (now called RINOs) support some fascist policies, but are not fascist.
