I think it very much is a matter of degree. I believe that most loving parents will come to accept and love their kids as they are, for their own unique selves, but what is heart breaking and difficult to accept is when you know your child can never be independent. For my son, that is not true: I am quite confident that he will someday stand on his own two feet, even if the road to getting there is going to be a bit long. He may even come up with the worlds next great invention He's fun and quirky and very HAPPY as a person. It's a total joy to have him in our family, and to know he is my son. There is nothing to drive us to want change for him. OK, the social issues can tear at me a little bit, but it's a pretty small thing, in the great big scheme of things.
But imagine if my son was always depressed. If he hated his life. If his talents didn't rise up, and his life was drowning in burdens. Then HE would want to be different. And, so, I would want it for him. If your child doesn't seem happy or able to function in any way in this world, you, as a parent, are going to want to do what you can to change that. It is our job, after all, to raise happy kids that will grow into happy adults able to stand on their own. Just how driven I would be would probably depend on what I believed my child wanted - I am, generally, highly child driven when I make my decisions, trying to be sure I do what they WANT for themselves, not just what I want for them.
I am very driven right now to change certain things for my NT daughter because of the simple reason that she is NOT happy. It comes from in her, part of who she is, and how to "fix" it remains a total puzzle (I will NOT just throw medication at her; I will avoid that entirely). But, yes, for her whatever it is that needs fixing, I want to fix it - because she does. And that is my NT child. No one comes without burdens. They just come in different flavors.
