No, you are asking the wrong questions and attempting to lump these abusive cults in with activities that don't compare. It's okay, program minds need to keep spinning themselves around to make sense of the world around them, we all understand.
Again, how many public schools MURDER their students?
How many fire departments MURDERED their cadets?
How many kids were at school against their will, taken in by kidnappers? How many firefighters?
First - you will never be able to compile these numbers, so you are pursuing a blind alley (which I think you are doing on purpose).
Second - these facilities do harm that is immesuarable even if the child is not killed. Emotional stress, emotional abuse, physcological torture are all activities included in the price of WWASP. Suicide is a tragic byproduct of this corrupt and fear-mongering system called WWASP.
But the data speaks for itself and it is comparable data.
There is no comparable data to programs becuase they are in a category all their own. Every comparison you list here is an accountable system. Schooling, Firefighting... they keep records and have requirements, training, etc. WWASP has none. It is an unregulated business who murders children behind closed doors, accountable to no one.
If you want to spend your time compiling data that you will never be allowed to get, by all means, go for it. Personally, as with many other ex-studnets, we know first hand the horror of these faciltiies and don't feel the need to compile numbers to convince parents otherwise. If parents ignore the true stories of horror, and ignorantly ask for statistics... god help their child.
