> Literally the only important thing in life, the basis of all value, the formation of self-identity, comes from communication with other human beings.

I think you're mistaking their sarcasm for sincerity... especially considering the emphasis on self-identity ironically juxtaposed as originating from a decidedly non-self activity, which has all the hallmarks of being intentional...

On the other hand, reading their other content leads one to believe that they may, in fact, be serious... hmm...

Human beings require interaction with other human beings to identify the self. It is impossible to live without others. Read up on solitary confinement sometime - enough time without human companionship will drive any human being (except the schizoaffective) completely insane.

Yes? That's completely true.
