Asperger syndrome (AS), also known as Asperger disorder (AD) or simply Asperger's, is an autism spectrum disorder (ASD) that is characterized by significant difficulties in social interaction and nonverbal communication.
A large majority of hackers have aspergers. A friend of mine, the famous hacker Captain Crunch, aka John Draper, is immensely talented yet has problems understanding normal human communication schemes.
It's possible that Crito has aspergers or is a swagtard like the Rap Genius guys. If he has aspergers, it's perfectly reasonable for him to not understand the point I'm making as his ability to pick up on nuances of human communication would be flawed.
In the swagtard case, he needs to defend his habit of wearing glasses indoors, otherwise his self-image would immensely suffer, and his ego would shatter. That's worse than death for those who judge themselves by their ability to be cool.
So how can you compare what I said to a rape joke? Nothing is humorous here, it's all very seriously logical.
