Many bishops protected priests who were child molesters for years, transferring them from parish to parish and allowing them to prey upon new children rather than turning them over to police. In the Catholic Church today, protecting the image of Islam appears to be job one: you can be a cleric who speaks out against the Church’s official positions (such as those on contraception and female priests) and in many quarters of the Church you’ll be hailed as a hero.
But the highly dubious proposition that Islam is a religion of peace has become a kind of superdogma that the U.S. bishops enforce with a stringency (and even ruthlessness) that they never display regarding actual Church teaching. You can reject every element of the Nicene Creed and everything the Church teaches, and still the U.S. Catholic Bishops will consider you a Catholic in good standing. But if you believe that Islam is not a religion of peace, you have no place in the U.S. Catholic Church.
