First, is it possible that someone adopts an ideology because it is (or appears to be) true, and then forms his personality according to that ideology? Does your adherence to moral psychology preclude the possibility that an ideology might be true?
Second, there is confusion about moral principles. Some libertarians do not hold that individual liberty is a moral value above other moral values. Whereas, individual liberty is a right, rights are different from moral values. One has a right to be free from government-enforced charity, and yet he has a moral obligation to be charitable. Your paper doesn’t seem to include the possibility of distinguishing rights from morality.
