Thanks for giving some examples! Does fascist count? I mentioned before that you can throw around "woke" at me, and I don't care. People aren't saying "how dare you call me woke" are they, in the same way they say "how dare you call me fascist"? Maybe WY's right and that's just my bubble and people are happy to own being a fascist.
Gammon is a good shout, but it's just more a rude insult. It's not a vanilla political term that has been weaponised, its a direct attack.
Boomer has nothing to do with left right.
Is "Tory" on its own used as an insult? "Tory scum" and other epithets sure, but its the word scum that's doing the heavy lifting. I could be missing that, though because I'm in Oz (where everything gets confused because the tories are the liberal party).
I'm not looking for or claiming high ground, but I have noticed a lot recently, especially in the US and often enough here in Oz, where someone with political influence will describe someone as "woke, socialist, radical left, liberal" with the full intent that those words are considered insults and are given meaning beyond their definition. The flipside that I don't hear is "conservative, reactionary, authoritarian" etc as anything more than descriptive (not sure what the equivalent opposite of "woke" is?). There are of course hyperbolic attack words that get used like "nazi", "gammon".
