Part  1
Great, I am in perfect agreement with your first two paragraphs!

The logical follow on should be:

Although we Catholics are convinced that our position against abortion is correct and extremely important to us, and even though we are horrified by any and all abortions, we have also formally declared in V2 that we will respect the conscience of all others. Therefore, even though we know the secular view that sees the fetus as not yet fully human is incorrect, we are restrained by our own principles from attempting to force our convictions on others by attempting to make our view the law of the land in pluralistic societies.

On the other hand, we will do everything in our power to reduce the frequency of  abortion. For example we acknowledge we ought to be at the forefront of the movement for explicit sex education about contraceptives, and also of the movement to ensure that everyone, no matter how poor, has access to contraceptives, in order to reduce unwanted pregnancies.
