I would suggest that to really inform his Catholic conscience,the good Professor should attend an abortion...perhaps a late term one...then he should attend the weekly meetings of a Rachel Vineyard (provided by the Catholic Church)group where those who chose abortion tell of the pressure they felt and the pain they have experienced as a result of their “choice”.
I do not make these suggestions lightly.
