There is a very fine line between teaching social rules and norms and "how to successfully integrate" versus brain washing and forced conformity.
The worst part is, I get that the early years for parents of kids on the spectrum can be torturous. Mine didn't even know what was wrong with me. They only knew that I had a "bad temper" (meltdowns), that I was "selfish" (lacked empathy), and that I was "clumsy," and so on. However, my parents also saw that I was smarter than many of my classmates, creative, and original. I can remember in vivid detail their struggle to help me fit in without turning me into another drone.
So, I am against forcing kids to adopting some fictitious NT facade, but I am also in favor of giving them the education they need if they choose how much to accommodate "normal" people's expectations. It's just such a fine line. When I was a kid, I needed someone to teach me the unwritten rules of NT conversation, but I didn't need someone to tell me I had to see things the way NT's see them.
Because my 'rents didn't know about the spectrum, they did the best they could. I saw specialists for a number of co-morbid conditions they did identify. They helped my sisters with homework, and they helped me talk to other kids. Fortunately, they also encouraged me to go right on being different/special - but only to a point. I wasn't allowed to hurt other kids' feelings, be disrespectful, or to be insensitive. I wasn't punished for things I didn't understand, but once they told me something I did was insensitive, I was punished for repeat offenses.
I don't know where the line should be drawn, but I am pleased with my experience. My parents struck a balance between teaching me to fit in versus letting me be my own person. Was it the right balance? Who knows. I'm sure they did their best.
But the behavioral training/ABA seems creepy to me. There is a line no one should cross with telling a child how s/he should think/feel. We want them to grow into free-thinking people, yet we don't want them to lack the skills to function in society. It's just a fine line, and it scares me.
