Autism

I think it's probably helpful to put words like 'normal' into their proper context- it's a statistics term, not a baseline from whence deviation is morally fraught or anything.

We're different, not worse.

Consider, if you will, the hypothetical in which you, a normal healthy human, visit Krypton and discover that the doors to their buildings are all high up, no need for stairs because *normal *people there can fly. In this sense, you are not accommodated in exactly the same way that a wheelchair-bound person is not accommodated when the stairs into our buildings aren't accompanied by a ramp.

On Krypton, you are handicapped not because of how you are, but because they don't accommodate that. On Earth, the wheelchair-bound person is handicapped because we don't always accommodate their needs. In neurotypical culture, being different only becomes a handicap when the people around you are unable or unwilling to accommodate you being you.

We didn't get the same degree of neural pruning when it was time for neurotypicals to get that, and it means we tend to process substantially more information- and the things our brain picks out as interesting aren't always the normal, expected ones.

The 'disorder' arises only when other people can't meet you halfway, it's not you.
