Why does everyone take Asperger's as a disease?

[soulofcerberus]

This thread = tl;dr for me but I read the first couple of posts.

My cousin is autistic, his social skills are down the gutter, he can't have anything near a conversation, repeats stuff over and over, and can't take no for an answer.

However he can write down the complete credits for over 50 movies just off the top of his head and can hum songs near perfectly after just hearing them once.

I feel bad for him, and being around him is always hard.
While there are advantages to having amazing thinking abilities like that, in most cases, the disadvantages outweigh any benefit.
