The question with Russ is, I think: Too many chromosomes or not enough? The fact he can't see the difference between someone who will most likely require help for the rest of her life, and him, who can do most daily tasks without difficulty, is not surprising. Disabled = special treatment in his mind. To him, it seems there's no difference between having a non-working face but otherwise fully capable, and being intellectually disabled, which is a significant disability.
I think Russ's mind is broken beyond repair. As someone said, he's delusional. I think he really does think people constantly insult him for his face, and that hordes of Taylor Swift supporters conspired to make him miserable. I would lay money on him having actual Narcissistic Personality Disorder in addition to being delusional and having a double-digit IQ. The fact he thinks he can take on the law firm of a major production company by himself and that he's going to make Heidi Klum want to fuck him with a shitty jingle, is a clear indicator to me that he doesn't live in the same world as the rest of us. Treatment only works if you admit you need it, and Russ doesn't think there's anything wrong with him.
