An example is the current use of 'conservative'. Conserve what? Conserve our institutions of higher learning, the abode of the best and brightest of our intellectuals? Conserve our newspapers, those beacons of free speech and the public's 'right to know?' Conserve our scientific exploration of the Earth's climate and the effect of our energy usage on it? You get the idea.
'Conservative' is a label which should be understood as someone who is anti-intellectual and, in many instances, evangelical if not fundamentalist in religious belief. Someone who, while embracing the fruits of technology, is suspicious of science and scientists. Someone who wishes to impose the straitjacket of his beliefs on a free society.
And that's just one label.
