“Gravely evil” sounds about right. Leaders? Maybe, of something. Catholic? It’s not for me to judge, but I hope the Archbishop excommunicates them along with their filthy money.
(Catholics United Against Catholicism, pronounced "Quack.")
I believe it was under analogous circumstances that Archbishop Joseph Rummel of New Orleans excommunicated Leander Perez and his crew in 1962 They were excommunicated for aggressively opposing the racial integration of Catholic schools in the Archdiocese starting in the 1963-64 school year.
Sometimes excommunication is the best communication.
