No Protestant has ever sexually abused a child. And no Protestant denomination has ever been part of any coverup of any abuse. For Protestants have imputed righteousness and therefore are covered by the holiness of Christ himself and therefore can not commit any sin that warrants hell. Gee I thought you would know this.
And I am not sure what or whom you meant we should forgive and forget. Forgive yes as CHrist tells us. But forget. I think we do so at our peril.
