Funny, but for me its just the opposite. It was my realization that abortion was wrong that drew me back to the Catholic church. When the rest of society was gleefully killing babies in the womb, the Catholic church stood almost alone for the sanctity of life.
Contrary to your comment it was science that caused me to become pro life.
And, it is science, especially hi-rez, 3-D sonograms, that are rapidly turning society against abortion.
So, thank YOU for your anti-religion opinion. Your atheistic views are your religion.
