Pejorative Accuracy

I was idly sifting through the American news (well, at least the US part of it) when I realised that three terms used pejoratively in such media could certainly be applied to me in some contexts. These three terms are 'un-American', 'useful idiot' and 'fellow traveler'.

I am certainly un-American. Actually, I am completely non-American. And I am also a useful idiot when I have to be, as well as a fellow traveler to those whose causes I sympathize with. There you have it, accurate self-pejoration.
