But that is refutable. You're not a true nihilist as long as you take advantage of the accoutrements of civilization, even down to the technology that enables you to make that post. You can avoid taking advantage of such technology in the spirit of "starting over" (even Pol Pot tried that) -- or you can say the technology around you admits of some advantages, which means limiting the nihilism/radicalism enough to pay credit to something around you. (To borrow from the postmodernists: "Not that there's anything wrong with that.") But for a nihilist that would be an unlikely reversal: the ego having stomped everything under its foot, is now making room for something outside of itself.
