I agree, Moomin. Lol, it's funny. Common aspie talk about how superior they are. Note how he says "aspies do but only to discover the scientific truth, the good of mankind". Such tripe! Most comments have no ulterior motives.
Is there something he has done that makes you doubt that he is actually kind and sweet? Willingness to help, overall happiness and lack of negativity, empathy, these are often reasons why they might call him sweet. You said one of them is sixty. She's probably feeling motherly towards him, and that's why she thinks he's sweet and kind. I get that a lot with older people, too. Your outlook on people is very skewed, and very wrong.
