You seem blind to the practical reasons against the Catholic doctrine.

I am not. But you are blind to the innate immorality of contraceptive practices, and your reasons are based upon expediency only. And if what is expedient is going to be lawful, then goodbye to morality. Slanderers of the Catholic Church have accused her of teaching the frightful doctrine that the end justifies the means. The Church has always indignantly denied such a doctrine. She has ever taught that men are not free to do what is morally wrong because they think they have some good end in view. But where the world used to say, “Those evil Catholics teach that one may do any harm that good may come,” it now cries, “Look at that tyrannical Church! She dares to tell us that the end does not justify the means, and that we are not free to do anything we like if we have a good end in view.” Once again I must say that you cannot have it both ways!
