You can’t just pick and choose definitions of a word. When you use a word, the most common definition of it is how you will be understood (depending on context). Otherwise I could say that poop is worth a lot and then say that poop means gold.
Moreover, sadly, many people do not even have the slightest idea of what certain ideologies are called. They don’t get further than “fascism bad nazi bad communism bad” without being able to make a distinction. This allows for easy manipulation of the masses by defaming anything you don’t like as one of these things. That’s all it is.
If you use a word that you don’t entirely understand, research the word, and if necessary, explain how you understand the word. Allows for good-fath discussions. Do not misrepresent it.
