CapriUni, I agree with you. 'Crutch' is now firmly ensconced as psychobabble.

I can't remember the title, but I recently read the autobiography of an autistic boy about 18 or 19. His mother sounded like a cold and demanding person. It seemed that every time his teachers suggested something that would help him, that she rejected it as a 'crutch.'

I translated that as "not good enough for me. I want him to be perfect."

For example, he didn't say his first word till age 7 (IIRC), yet she refused to let him learn Sign, because that was 'a crutch.' When I think of that poor kid being kept from communicating, it makes me so mad. Later I saw a video of him, and his speech was still so unclear at 18 that he could have benefited from Sign.

So how do we deal with "crutch"? Call it by its real name -- ("Please spare me the psychobabble. We have a problem here that needs solving.") -- and it will shrivel up and disappear.
