I, too, would describe myself as a nihilist and statist of sorts, however, I don't really subscribe to the Stirnerite-esque egoism you seem to. Manipulating other people seems like a bad thing to do however, unfortunately, I can't find any philsophical basis for denouncing it. The best I can do is say "I don't like it" which is, obviously, nothing more than crass emotivism.
