Right, there were no sexual deviants or perverts before Vatican II; please. Dogma does not change because, by its very nature and origin {i.e. Divine} it can not chanhe.—mjmchale  Biases and prejudices all stem from history, i.e. “before Vatican II.”  Whether or not dogma can change depends on the definition of dogma.  In the meantime, perception of dogma does change.  Understanding changing perceptions of dogma is a function of theologians.  That is why the censure the American Association of University Professors is imposing on The Catholic (Pontifical) University of America is an abomination before God and humanity.  The censure is due to the fact that CU policy will not grant a hearing before firing a professor.  Even Jesus gave Satan a hearing.  There is nothing against faith and morals in listening to a professor, before firing him.
