They may lose a few of the older, thoroughly brainwashed Catholics, but the younger generation is much wiser, and much more liberal than their predecessors. They live in the real world, not a mythical world created by their ancestors.
The catholic church has seen a major upheavel in the last few decades and I predict the future of the catholic church and it's teachings is in grave jeopardy. Before long the pope will become merely a figure head with no authority over any, but the most easily manipulated, and those are a dying breed. You would be surprised at the number of young "catholics" that believe in abortion. They are sick and tired of a figurehead pope, telling them, how to conduct their sexual activities and the propagation of their species.
As a matter of fact I have MANY, and I do mean MANY people with whom I converse, including an X-Priest, who happens to be one of my best friends, (most of my friends and half of my relatives ARE catholics) that admit they are tired of the worn out old pope trying to tell them what to do, especially when it comes to having children. They no longer buy the "go forth and multiply" BS crammed down their throats for years. They have taken responsibility for their own methods of birth control, regardless of what the "pope" says. They are intelligent, highly educated individuals, who are no longer under the influence of the church or it's archiac teachings.
So if it is defeated, which I doubt, it only goes to show that there are still to many brainwashed, old cogers still alive to pose a problem.
But it won't last long, they are all old and dying off, and it's a new day and a new generation of intelligent individuals (unlike in the past) unable to be brainwashed by the tales of old!
