Good for him if he's happy - if he's really happy. Keep in mind people (autistic or otherwise) do lie to themselves sometimes. You can get used to most any status quo, but is that happiness? I don't think real happiness comes from accepting less than you can be. Perhaps that's just my opinion. Now I'd bet my post at least made him start thinking, even if he isn't in agreement. He isn't required to agree anyhow. You aren't required to censor his statements either - I can handle it. Perhaps you think I can't because I told you I'm Autistic? See? He can call me an asshole if he likes. I'm okay with it. I don't need anyone to use kiddy gloves on me.
What you have to realize is that people don't have to live up to your expectations of how they should be.
Interesting thing to say. I'm telling you that
Autistic people don't have to live down to lowered expectations... which subconsciously you're setting for him. As for him, people tend to subconsciously try to match the expectations placed on them. And that's why lowering your expectations is not doing him any favors. On the contrary - everyone (autistic or otherwise) could use a push on the back now and then.
