As someone with family on the autism spectrum myself, I’ve found they’re usually fairly open to whatever the facts are whether that disproves them or not. There’s a lot of overlap at times between narcissistic traits and autism, are you sure he just wasn’t a narcissist? I say that because refusing to accept the rationalization of what may be a bad idea just sounds dumb. (The bumper stickers made stand out to me too).
Alternatively he was just someone with autism who is narcissistic and with an ego who refused to accept any new information that countered what he had settled on.
