Now the fact of the matter is we Catholic profess two moral positions: (1) Abortion is immoral because the fetus is fully human and thus immortal, and (2) all immortal humans are entitled to freedom of conscience.

Our problem at present is that in modern democratic societies these two fundamental moral values are in direct conflict!

V2 formally confirmed the long standing Catholic value of freedom of conscience, and we Catholics worldwide are very good at demanding freedom of conscience whenever OUR FREEDOM is threatened.
 
However, freedom of conscience above all obliged us to grant THEIR FREEDOM to others who do not share our morality—precisely point of V2.

So we are against abortion, and we must fight any law that would impinge on our right to NOT abort. But at the same time, we believe in the freedom of conscience of others, and so the only way to be absolutely true to both of these Catholic values is to support laws that allow other to also follow their conscience.
