Take the case of "fascism".
When you can see clear as day that the person who is accusing you of fascism is a fascist, they aren't projecting. They're talking about something ELSE.
Basically, in the case of fascism, the basic set of fascist government controls are the default assumption of reality for a whole lot of people. The government is supposed to control every part of your life. The government is supposed to make you moral and good and reflect "justice". The government is supposed to do this by picking winners from the good people and losers from the bad people. The government is supposed to control the way people do business, how businesses (and farmers) function and what they produce. And people should be made to cooperate with this control because they are part of society and society is dependent on everyone being in compliance. This is simply the Truth. It's how the world works and how the world is supposed to work.
The Socialist Nationalism, State control of "private" business, the "incentives" and punishments levied by the State to make you think or live in the way you're supposed to live don't actually have a NAME at all. It's just the way things are and the way they are supposed to be. There's no interrogation of premises or even understanding that there ARE premises.
And that's where we are.
When the "good" people wield this system of unnamed control it's called "democracy".
When the "bad" people wield this system of unnamed control it's called "fascism."
If you claim to be against this system of unnamed control you're just lying. And also a fascist.
