I have finished revolutionizing the neoeuphoric infliction of my internal terror. Your children who have ridiculed me, who have chosen not to accept me, who have treated me like I am not worth their time are dead. In retrospect Rand's words can be taken as an ominous warning. According to Rand, the anti-conceptual mentality leads to tribalism. Those with anti-conceptual mentalities cluster into social groups in order to feel safe.

Rand is quick to point out the difference between tribalism and civil interaction. Tribes are not bonded by ideas or values, but rather by fear of the unknown, the unfamiliar, the new. The arrogant jocks and debs still sublimely sail over the cowering nerds and wallflowers, who compensate by organizing their own pecking order, in minute gradations of status painfully obvious to everyone. In my school, a large group of us were interested in athletics as well as intellectual pursuits such as debate as well as social functions. Cliques seem to be more entrenched among some groups of students and at particular schools.
