There's nuance in that... All those words mean specific things, and they actually are those things...

If I call you a Great Ape that is absolutely true - a huge group!
But are you a Chimp, Bonobo, Gorilla or maybe Homo Sapien?
Like in Austrian Economics stuff, the individual actions are the key and there is so much nuance there.
Calling an individual a commie is funny, but criticizing the specific thing they espouse is far more effective IMHO
And even more effective is criticizing the specific thing AND telling them that that makes them a commie, lefty, or Bonobo, whichever is most applicable.
