As someone said before, they must be a bit ignorant. I have an aspie son and an NT daughter, there are strenghts and weaknesses in both types. Just because your child is NT doesn't make him or her perfect, and knowing your child is autistic doesn't mean you know everything you need to know about him or her....there is personality, intelligence, kindness, there is a lot to discover in any type of child and you're always amazed when you get to know them as they grow up, being autistic doesn't change that.... being NT either, by the way.
I was a little bit scared that my daughter might be NT, I pictured a heartless bully , she started lying at 18 months old lol........ but what made her different also made her special, the first time she brought me a decorative flower plate thingy and a pen, and proceeded to feed me imaginary food with that, the pen being a spoon, she was not at all verbal yet, she barely walked, and I thought.......oh god, how SMART is that child?! ! as every parent probably does. I now find her attempts at lying pretty cute (the cat farted is my favourite lol....), and i know it doesn't come from a mean spirit or anything, she's just a normal NT kid who needs to be taught right from wrong (which I never had to do with my son, but I adapted, on the other hand she never had to be taught safe from deadly, I never once had to save her life, when my son at her age was a huge danger to himself, so really there are good things in both cases)
