Since at least the 1960s, conservatism in America has come to be dominated by something we might call "procedural conservatism" - a conservatism of process rather than content, of means rather than ends.
Equality of opportunity.
Equality before the law.
Today's conservatives even fancy themselves champions of "free speech", "religious liberty", and so forth.
Not that there's anything wrong with the above formulations, if understood in a non-ideological way that doesn't interfere with common sense. But American conservatism has degenerated to the point where these are taken to be ends in themselves. Lacking a concrete vision of what a good society is supposed to look like - and having a visceral fear of being perceived as "imposing" their vision on anyone - conservatives have retreated to an amoral philosophy of process and procedure.
Therefore, let us remind ourselves: a society may scrupulously observe all the procedures outlined above and still be fundamentally liberal and on the fast track to perdition.
The substitution of amoral political means for moral political ends has a twofold effect: 1) it fosters an attitude of indifference with respect to the moral character of our people and institutions; 2) it creates a dogmatic inflexibility when it comes to process, which is meant to be servant rather than lord. The combined effect is the death of conservatism as a meaningful force for good.
