Twelve years ago I volunteered to run summer camp activities with autistic kids. These kids had speech problems, and were constantly shaking, arms curled, their thoughts were aloof and obsessive. Yes there was a spectrum, but there was no doubt who was autistic.

Newly found, or self diagnosed persons have clarity of mind that was completely absent from traditionally autistic persons.

Frankly, if you can think straight you shouldn't be let off the hook. To speculate, perhaps our society is getting bad at instilling social behavior, as kids are increasingly isolated.
