Chaminade would have expelled the boys before they even made it back from NJ!
So, they can because they are private, so what. Suddenly the Brothers (men in dresses), would be such tough guys. I don't recall in my version of the bible where Jesus was one to rush to judgment. I recall stories of a man who worked with the imperfect among us.
Yes Cham would spell but so would Friends, Portledge, St. Ants, k-berg, Sacred Heart, St. Droms, and St. Mary's if it happened there.
Then it becomes a transfer issue for another place.
However some of the schools mentioned might accept these kids as transfers.
Looking at you St. Dons.
