The most damage being done to the C of S in the US was done by others. In other countries, there has been far, far more damage than in the US.
But Marty has gotten some out. For that, he's done alright.
The BBC has used many ex's for their interviews. Marty did not spearhead that. He holds back on the really damaging evidence and instead generalises, whereas others with more courage and integrity have not.
What will close the C of S in Britain is when Australia closes it down - and the recipricol church laws will no longer apply to the C of S there.
What is needed - and what is missing - is the US media to do some stories. If Marty can crack that open, then we'd all be very pleased.
