They clam up because they are not truly interested in a debate. You hit the nail on the head when you used the word arrogant. This is what Hyde is all about, the arrogance of the Cult leaders and followers. They live in a world that you and I cannot understand.These people are delusional and full of themselves.
I see one family on the website who was at Hyde years ago when I was there. Truth is that after many years of having their kids at Hyde and participating themselves in the Hyde process, and now being fundraisers for Hyde, they are exactly where they have always been, completely dysfunctional, unable to function without a crutch. How has Hyde helped them? These people are still stuck in the same place as when they enrolled at Hyde. The only difference is that by now they are in the "inner circle", have learned the Hyde lingo, and are now recruiting for Hyde.
I saw another parent listed who is still very involved in Hyde. Again, this is a lost soul and if he truly had learned and grown from his experience at Hyde, he would have moved on. I personally do not believe that Hyde helps a person grow. If anything, I believe that Hyde teaches you to lean on them for all the answers in life. Seems that most of the "HAPA" parents are still involved in Hyde because they still have deep issues that are not resolved and probably never will be. Certainly Hyde is not capable of giving them the professional help they need.
Very sad that these "loyalists" don't understand that they haven't grown the way they might think, they have only conformed more to someone else's way of thinking. This is called, "mind control" and being under the spell of a Cult.
