I am a bit confused by your response. One cannot seeks answers without questions.
I have read three of Rand's books and excepts of others. The very questions bdame presents are the questions a Christian must ask him/herself in response to Rand's philosophy. While there is much a Christian can acknowledge as worthy, Rand's utter antagonism against altruism cannot be reconciled with the Bible. Unconditional love cannot be reconciled with pure self-interest. I could go on, but bdame has valid points. I respect Rand's views on some things especially art in that it should uplift or focus on what should or ought to be rather than lie down in the gutter of man's lowest instincts, but that does not mean I adopt her philosophy in whole.
