I have days. On some days, it's positive. It helps with various things in life, it gets me through college easily and helps me understand why I am me. On other days, it's negative. I hate it with a vengance when I watch my friends and wonder on earth I can't be "normal".
But the majority of the time, I'm quite happy with it. I don't want a cure and I'd reject it even if they did come up with one. I'd happily look for the /cause/, out of pure curiosity but I'm not interested in any cure.
It seems to me that Asperger's is only negative to those who either don't understand it or want nothing to do with it.
