Absolutely correct. Whenever I get a chance, I recommend George Orwell's essay "Politics and the English Language', as fresh today as it was when it was written in the 1940s. (It's available many places on the Web. Just Google it!)
But again, note that the disease has infected us all. See the rules of the forum for "racism", see the frequent racism threads and arguments, they are not about the existence of this malady, that concept, sad to say, is taken for granted, it is transparent. (I maintain that "racism" is a liberal invention, and an obnoxious term for the natural phenomenon of ethnocentrism, intended to suggest Dr Mengele, the Nazis and such.) And that is the disease we share with the liberals, and will continue to do so, until we start ridiculing the whole idea of"racism", until we demand explanations and definitions.
I think the strategy employed by the republicans and all the "compassionate" conservatives in general is not wise. Instead of preserving the conservative ideals as the core of their ideology, they compromise in the hope of attracting some undecided votes, while gradually undermining their traditional voters and most importantly eroding conservative ideals.
