There are a lot of opinions upon this subject but I believe they did the right thing.

I chose Catholic School for my family because the teachings of the Church are dear to my heart. When the schools no longer reflect the values of Catholic teaching, they will be ineffective.

This is a dumb argument. The young Lesbian student decried that the prohibition on allowing her Lesbian friend was a blatant form of "homophobia", is false. There was no discrimination of her person, which is a clear distinction from same-sex behavior and activity. A truly homophobic institution would not even allow her to attend the school and receive a world-class education.
