Trid, when you say that one must agree with the magisterium 100% if you are to call yourself a Catholic, most people here would say that you are wrong. As you know, I reject Humanae Vitae. I think that that not ordaining women is both unjust and sexist. Yet these disagreements do not mean that I reject the Catholic Church. I subscribe to the creeds in toto, for example. If I were to reject the real presence of Christ in the Eucharist, then one could reasonably say that I had rejected the Catholic faith. But saying that my getting a vasectomy was the moral thing to do doesn't even come close.
