I see little objectionable in the document to which you linked in your post, but that statement of principles is focused on economic policies, not on social policies. For what it's worth, I would disagree that "limited government, individual freedom and personal responsibility" are the primary foci of Western civilization, which is centered upon the related but different concepts of fealty (to Cross and Crown), duty (to God, family, and liege) and solidarity with the common weal. The idea that "government has no money nor power not derived from the consent of the people" is an idea of the pagan/humanist "enlightenment", not of the Christian civilization from which it sprang; such thinking inevitably leads to contradictory ideas such as
While recognizing the harm that drug abuse causes society... [we hold that] per the tenth amendment to the U. S. Constitution, matters such as drugs should be handled at the state or personal level.Such a policy towards drug abuse would of course be the same as no policy at all; in such a society individuals would be free to do as they liked with themselves or their property, regardless of the effect of those actions upon the moral or physical environment around them. In a truly Western/Christian society, on the other hand, those private actions that tend towards the destruction of the common ethic of society (drug abuse, sodomy, bestiality, Satanism, etc.) or of those things held in common by society (the physical or esthetic environment, etc.) are justly forbidden by custom and (where necessary) by law. In an atomistic, libertarian society, every man is an island, reponsible to nothing but his own nerve endings; in a traditional Western sociiety, individuals are organically integrated into the society they inhabit, and responsible to their parents, social superiors, princes, the Church, and to God for their actions. The traditional Western view is that liberty consists in living by the natural law, but that no individual has a right to act as a corrupting agent within a society by transgressing that law. That way lies only chaos -- the ultimate negation of individual liberty.
The GOP must decide as a party whether it is going to represent the libertarian, humanistic, atomstic worldview of our modern world or the conservative, Judeo-Christian, communitarian viewpoint of our traditions. If the decision is in favor of libertarianism, then the U.S. political scene will become the province of two liberal parties -- one left-liberal big-government party, one right-liberal big-business party. Either way, conservatism will become a thing of the fringes.
