Funny, the two most common labels I am hearing these days are not on the list: 'liberal' and 'conservative'. In political discussions a lot of ideas are suppressed - or at least verbally dismissed - using these labels.
Don't forget "moderate." Nobody liked Giuliani's being moderate, no no no. You're not safe ANYWHERE in the scale. Avoid it and you're "apathetic." Get too complex and you're "elitist" or "flip-flopping" or "hostile" (if the right crowd catches you trying to explain things).
While he was too moderate for some (as was, for instance, Clinton on the other side), can you find me an example where "moderate" was used as a term of abuse against Giuliani?
"Moderate" really doesn't seem to belong on the list. I can't imagine anyone ever looking shocked and saying "That's such a X thing to say" when X is "moderate", but it seems to fit for most of the other examples.
Even deeper: The American free-market libertarians pulled a coup when they were able to redefine, in public discourse, what it means to have 'liberty' (compare the definition of 'libertarian' ca. 1900 Europe and ca. 2000's USA).
In what sense? The progressive movement as currently constructed is not enamored with neither Leninism nor Stalinism, though there is sometimes a smidge of respect for Trotsky.
...Man. I miss George Carlin.
