Stephen Mace took the time to respond himself to my comments, and noted two huge issues. First, his discussion of Nulls takes place in Seizing Power, not Taking Power. Second, I also got the essay in question wrong. He discusses the Nulls in Hierarchy: Ready Brain for the New Demiurge, not in For Those Who Would Subvert the Status Quo. This was extremely sloppy my part, and tells me that I need to start citing things like a bastard again to avoid ever making that mistake again.
Finally, as my responses to his comments show, I don't know if I understand his concept of the Null entirely anymore. In short: I did exactly the things I criticized, and opened my mouth when I probably shouldn't have.
This brings home the need to start citing things again - and figuring out how to do that properly in Wordpress - and my need to pay stricter attention to what I write, rather than just writing to write. Finally, maybe it's time for me to start seriously working with an entity that deals with some compassion or something less aggressive, because my tendencies are getting out of hand.
In short: I really am a dumbass, sometimes, and that shit is unacceptable. Now, to go make some edits.
