The US Conference of Catholic Bishops isn't the entire Church, this position isn't upheld in the Catechism and this is not a statement by the Pope.
What's so difficult to understand about those facts?
The bishops' position IS upheld in the Catechism. If you go to the link, you will see that their position is not far from yours.
You somehow want to leave the impression that Mahoney is acting against Catholic teaching, and that is most assuredly NOT the case!!
