Bad puppy, someone rubbed your nose in too much poo, I think.
"Did they also end the practice of emotionally disturbed kids giving consequences to other emotionally disturbed kids?"
Why do you assume the kids at the school are all emotionally disturbed? And do you understand that a "consequence" is just losing points? Do you know about the body of research that fully supports A. increasing privileges and responsibility in increments proportional to quality of performance and B. peer tutoring?
"Do you deny that mail to parents are censored?"
Absolutely. What you're confused about here is the level of parent/family involvement. Letters to and from parents are completely private. The only exception is if the PARENT sends a copy to the therapist or family rep.
"Do you deny that education is self paced which is another way of saying no classroom teaching?"
Again, absolutely. Self-paced is your term, and refers only to the speed with which a student completes something. Self-guided describes an individual plan for every child, something private schools have been striving to create for about twenty years. The student gets to run the show, and that's as it should be. Your assumption here seems to be that the teacher is not available. This has no relation to reality.
"Do you deny that isolation is used for punishment?"
Isolation is not used. Period. It is "intervention"--by clinical definition a completely different animal.
"That purple room looks mighty small and uncomfortable for a three day or longer stint."
Intervention looks like this: a student who is escalated goes to the intervention room, accompanied by staff. They can choose to stay escalated, but most are happy to try other available means of handling things: have a therapist come over and talk, have a staff they feel confortable with come over and talk, have an upper status student (one or a few) come over and talk. If they just don't want to talk, that's OK too.
By staying relatively calm for half an hour, the student shows a willingness to act in a safe manner, and heads back to wherever he was before that. The exception? Some kids want to stay and relax; that's OK. Some also go there at their own request, for a time-out.
Bottom line? It's up to the student, every step of the way. That isn't isolating, it's empowering.
