I tend to be bothered by Egoists, Nihilists, and, Post-Left Anarchists.
Post-Left Anarchy really kind of gets at something, but, I don't think that they adequately cope with that the theory hazards being co-opted by the far-Right via that it does lend itself to be subverted by crypto-Fascist discourse. I honestly haven't had too many interactions with Post-Left Anarchists and could just be assuming too much, though.
I just see Nihilism as being misguided. To my understanding, the philosophy of negation is just Sartrean Existentialism. I tend to use "nihilist" negatively and wonder if I'm not being unfair to the school of thought. The way I see it is that Nihilism is sort of like a coping mechanism where a person just kind of shuts down faced with the incapacity to cope with the human condition. You should not desire that language be rendered meaningless. I guess I see Nihilism as just simply being the pejorative levelled at Existentialists. I think that you should try to reinject meaning into the world. I did a reading group on Nihilist Communism a while ago which I like because they bring up a lot of things that I am interested in and have a few really great rambles like the one that begins with "Bowling Green. Sewing Machine." They offer transcendence in partial jest and in partial sincerity at the end of that text and, in retrospect, I can't help but thinking that all that they would transcend would be Nihilism. Perhaps, I just don't give the school of thought enough credit. I honestly haven't actually read too many Nihilist texts.
Egoism, I see as being resultant in exclusive cliques who fetishize as fucked up of forms of Individualism as humanly possible. This mostly stems from Egoists that I've met online and could just be off base as such parties are likely to be fairly isolated and anti-social. I don't think that the actual school of thought is really like this. While I'm not an Individual Anarchist, I am sort of partial to the theory. I am, however, against the aporia of human relations that predicates them upon the "findings" of Game Theory. Perhaps, I just haven't met the right Egoists, though. I honestly don't think that the school of thought can really be all that bad.
Does anyone have or care to issue a retort? I'm an Pacifist and a far-Left Anarchist and so I'm sure that my particular inclinations are sure to bother some people.
