Leftists take a LOT more offense when it is pointed out that they are fascists. They’re kinda used to being called socialists and Marxists.
?
I’ve not considered marxism and fascism to be interchangeable even though they both operate through totalitarianism, and fascism is usually (I think - I’m wading in deeper water here) more commonly associated with a far-right gov’t. (think South America). So if I’ve got it all wrong, I’d be interested in how they are the same.
