I do not believe that you have studied the epistemology and metaphysics of Objectivism -- most likely you have considered the principles of Objectivism (which are but the logical end results of the epistemology and metaphysics), then dismissed them because they go against the Christian morality of self-sacrifice that you have already accepted as truth (on faith).
Religion is an early form of philosophy -- the first attempts to explain the universe, to give a coherent frame of reference to man's life and a code of moral values. It was created by man before men graduated or developed enough to have philosophy. As philosophies, some religions have very valuable moral points however. They may have a good influence or proper principles to inculcate, but in a very contradictory context and on a very malevolent base: on the ground of faith.
The good, say the mystics of spirit, is God, a being whose only definition is that he is beyond man's power to conceive -- a definition that invalidates man's consciousness and nullifies his concepts of existence. Man's mind, say the mystics of spirit, must be subordinated to the will of God. Man's standard of value, say the mystics of spirit, is the pleasure of God, whose standards are beyond man's power of comprehension and must be accepted on faith. The logical conclusion of this is that the purpose of man's life is to become an abject zombie who serves a purpose he does not know, for reasons he is not to question.
I won't go into the evils doctrines of original sin and altruism (that you are sinful simply for being alive, and that sacrificing everything you love, seek, own or desire -- even your own life -- to the benefit of any and every stranger, is a moral principle) here, as I didn't intend for this thread to be a religious debate.
Let me close by saying that I find it unfathomable that you believe that being an Atheist is to "live a life of hopelessness" -- especially as opposed to being a Christian. As an Atheist I am my own highest value, and my own happiness is the moral purpose of my life. Its quite liberating, and I enjoy every single bit of it to its fullest extent. I find the notion of living a life in religious servitude extremely stifiling.
Constitutional Republic, of which only role is to protect all individuals from the initiation of force from others. In order to defend individual rights, government's role must be limited to a strong military, police and justice system with a supreme court whose judges must be held to account by the people for any action which would not provide the protection of individuals as described in the constitution.
You might want to read through what Ayn Rand has said about the Libertarian Party (and the anarchists therein). Its not only interesting -- its quite entertaining. ;)
The English philosopher Lord Bolingbroke said: "History is philosophy teaching by example". On this, I am in full agreement with him on -- and frankly, its the strongest argument in favor of Objectivism. The epistemology and metaphysics of Objectivism establishes the true "axis of evil", namely that of collectivism, altruism and mysticism, and history reaffirms this as true, for all to witness. In any case, your argument is somewhat self-contradictory: It is when you put too much faith in the natural virtue of human nature that you trust and allow humans to rule other humans. Objectivism does not make this error.
