The staunchest conservatives advocate a range of changes which differ in specifics, rather than in number or magnitude, from the changes advocated by those considered liberal…change, as such, is simply not a controversial issue. Yet a common practice among the anointed is to declare themselves emphatically, piously, and defiantly in favor of 'change.' Thus those who oppose their particular changes are depicted as being against change in general. It is as if opponents of the equation 2+2=7 were depicted as being against mathematics. Such a tactic might, however, be more politically effective than trying to defend the equation on its own merits.
