Not many people in the US or anywhere for that matter identify themselves as communists anymore, or even socialists.
Of course people are not going to identify with the failed political ideology responsible for more deaths than any other in the history of the world.
But one of the things the left is fucking good at? Rebranding.
But that doesn't mean we are not staring at the same toilet full of shit.
Also... in my lifetime I can't thank of may words that seem to be more incorrectly used that "fascist". I think most people using it have some smeary definition in their head that they equate with "the beliefs of people who I think are bossy and mean". And this is the picture they hold in their head as they raise their fists and command some innocent couple trying to eat dinner repeat the words the (actual) fascists are screaming at them.
Irony abounds.
