IE You know I believe you are disappointed with ABA because what you got was disappointing, not because there is anything fundamentally wrong with ABA.
Perhaps it is the difference in stages between our children. However, perhaps I am not being consistent with my own strategies. Usually I say that provided ds has given something new and scary a decent try then he can make up his own mind whether it is for him.
So for example when he was 3 I had to force into his mouth some rice-pudding that I had made him (this isn't ABA btw just to be clear) because I knew he would like it. I had to force it on a spoon into his mouth because he refused to touch it.
In defiance he shrieked and spat it out immediately. I didn't react.
Then he got a spoon a wolfed the lot.
I took him to join a glee choir recently. There was a trial session and then you had to sign up for the term. I insisted he attended the first session for the full hour. He was uncomfortable and a bit anxious-looking and I watched carefully so I could pull him out if I needed to. He struggled hugely compared to the other children who followed the instructions beautifully. He had to learn a song AND a dance which was tough and he didn't manage it.
I negotiated a second trial session and on the way to it the following week he insisted it was the worst thing I could ever put him through and made a loud protestation.
Now I have no idea what happened in the week before his first and second session, but perhaps due to the strengths of his memory and imitation skills he struggled a bit with the first 20 mins and I felt absolutely awful for puting him through it but for the last 40mins he was clearly one of the better singer-dancers, encouraged to 'demonstrate' and all the way home he was complaining that a week was too long to his next session.
So I suppose unless it is harmful to a child I like to keep as open a mind as possible that something within the session will appeal, even if not immediately, at some point.
I am not trying to make my child 'normal'. I am trying to give him as wide an experience as I possibly can within the constraints his own disability imposes on him in order to widen his experiences enough for him to have the biggest choices later.
I am happy to admit however, that this is probably a whole lot easier with a 6 year old than a 14yr old (regardless of disability).
