Well, when a political party works to empower the already powerful, so long as they are the right kind of American, persists with policies that are designed to lead to the early demise of quite clearly demarcated 'less-than' people, i.e. eugenics by the back door (and bearing in mind that Nazi Germany looked to America to understand how to treat its minorities)... if the jackboot fits.
Oh, and how long has the GOP and its followers been calling liberals 'libtards' and Democrats 'socialist' and 'communists'?
