Part 3
Please note that I do not prescribe the restrain I advocate for Catholics on this issue as a moral principle for others. The American value of democracy as the way to determine laws is not challenged as a very good way for humans or organize themselves in polities. It is just that we Catholics on this issue find ourselves stuck between two critically important moral judgments: (1) abortion is wrong, because the fetus is already immortal, and (2) we must constrain ourselves from impinging on the freedom of conscience of others. 

It is precisely because we acknowledge that without our belief in the immortality of the fetus, we recognize as rational the contrary (and false view) that the fetus is only potentially human. It is in particular because we recognize the rationality of the arguments against us, that restraint ought to be obvious to all Catholics. 

Unfortunately this in not case. The reason for this is to be found in the moral development schema of  Kohlberg,
