I mean, to pick what is perhaps the easiest example, wanting to abridge speech is anti-American by its very definition.
It is possible to have a thing that is anti-American. So I'm not sure what good it is to reject the term altogether.
Ah, I see, it's the same as "un-American", only without being a word too onerous to use (yet) due to obvious historical implications.
It could e.g. be "anti-democratic" by a universal definition of democracy and civil liberties which no single country then gets to fork and redefine...
