Bonnie, you will get no argument from me that abuse has not been handled properly by our denomination. It has not been handled by most of humanity properly over the ages, either. IMO, there is a slow evolution towards breaking the pattern in both but so many are still being damaged.
The only realistic answer may be for each person who cares to attempt make a difference in their sphere of influence... speaking out, calling for accountability and looking for ways to bring healing to the victims and justice to the abusers.
Silence is not golden, it is viciously cruel.
