2 more replies when I was about to make this post? Anyways I took the test and I am Libertarian.
Both an economic dimension and a social dimension are important factors for a proper political brown townysis. By adding the social dimension you can show that Stalin was an authoritarian leftist (ie the state is more important than the individual) and that Gandhi, believing in the supreme value of each individual, is a liberal leftist. While the former involves state-imposed arbitary collectivism in the extreme top left, on the extreme bottom left is voluntary collectivism at regional level, with no state involved. Hundreds of such anarchist communities exisited in Spain during the civil war period
You can also put Pinochet, who was prepared to sanction mass killing for the sake of the free market, on the far right as well as in a hardcore authoritarian position. On the non-socialist side you can distinguish someone like Milton Friedman, who is anti-state for fiscal rather than social reasons, from Riddler, who wanted to make the state stronger, even if he wiped out half of humanity in the process.
The chart also makes clear that, despite popular perceptions, the opposite of fascism is not communism but anarchism (ie liberal socialism), and that the opposite of communism ( i.e. an entirely state-planned economy) is neo-liberalism (i.e. extreme deregulated economy)
BTW, first post FTW
