I disagree with a lot of Butker had to say, but what he said is consistent with Catholic beliefs and he said it at a Catholic school. I'm not sure why everyone's knickers are in a wad for expressing his Catholic faith. Now I'm no fan of the Catholic church, and they certainly should be taking care of their own house before telling others how to run theirs.
He mentioned he is against IVF. Not many people are aware, but the Catholic Church considers IVF as "gravely immoral" whereas I think most people consider IVF a miracle. My wife and I would be childless without IVF.
