It is fortunate for you that no Protestant has ever done anything wrong.
You just earned an F in logic 101
What Protestants have done or have not done is completely irrelevant to the actions of the Catholic church. There is no linkage to the two. Just the same as any transgressions by Protestants are not excused by those of the Catholic church.
The "yeah, well what about what the other guys did"? excuse is bunk. Any entity's actions - good or bad, be it a person, a church, a government etc, stand on their own.
