I have seen several references to people being Aspies, but I've seen too many "stealth" minorities (religions, lifestyles, preferences) claim celebrities for their own with no real evidence. Pagans do it, and I know a lot of gay people who will confidently tell you that any actor you like is gay.
But yeah, in this case, I'd say Ackroyd is a reliable reference.
