I wasn't meaning like she wisely decided to not involve her self in a big mess that had nothing to do with her, that would be social awareness.
I was meaning that since the issue (Nux's video and the VShojo response to it) didn't specifically involve her and she had nothing to add to the conversation, she never even considered saying about it like snuffy did.
I have met some autistic people that were like that, if it didn't involve them they saw no reason to comment or even pay attention to it. One guy from back in highschool was the only person present at a fight not involved with it, but when the principal asked him what happened the guy said he didn't know because he tuned it out and kept reading his book as the fight was happening 20 ft away,
