There is no way he can function without ABA therapy which he has been doing since he was 5, because that's when the Canadian government started to cover part of the costs. My friends are close to poverty levels because ABA therapy is over $80,000 per year and he has to pay about half of those costs.
The idea that someone such as yourself, would come in and say that this kid is being "forced into a box" is so offensive, it's astonishing that someone could say that. Without ABA therapy he wouldn't be able to be brought outside in the world. My friend's greatest fear is that he and his wife will die and no one will take care of him, and he will either be incarcerated or homeless for the rest of his life. ABA therapy is the ONLY thing that works, and saying that it should be banned is disgusting.
