“That conservatism is in too many ways a mirror image of the liberalism that it professedly opposes. Its commitment to a way of life structured by a free market economy is a commitment to an individualism as corrosive as that of liberalism. And, where liberalism by permissive legal enactments has tried to use the power of the modern state to transform social relationships, conservatism by prohibitive legal enactments now tries to use that same power for its own coercive purposes.”
