Left vs Right comes from which side of the French king members of the états généraux were sitting before the French revolution - those on the right were monarchist, those on the left were in favour of the republic. In other words, both were in favour of the state. Obviously all this was a long time ago, and most people aren't really aware of it, but that doesn't mean it's not relevant, because the underlying assumption still persists that the whole spectrum of conceivable politics need to be enacted through the state. That's still true, whether it's social-democrats, liberals, leninists, greens, whatever.

I think one of the most important things we need to get across is that worthwhile political changes can only be achieved through direct action outside and against the state, parliamentary democracy and the various structures of class collaboration, and that means questioning the left vs right thing.
