Let me just throw in my two cents.
/b/ is full of social rejects, more or less? I have a theory that its users (and myself) could possibly believe in sincere "love", at some point, and were rejected because of that, at some point. And you know the rest of the story, we're all emotionless monsters now. (or act like it)
I'm not trying to be a psychologist or anything. Just wanted to bring it up.
