I agree that totalitarianism is used pretty vaugely there, but I think it means the sort of pure totalitarianism you get. Like 1984. Stalin or Mao, though claiming to be communist would fall here, for example, because there policies basically came down to 'Everyone do exactly what I say, when I say, all the time'.
But Stalin and Mao were Socialists. Socialism is not marxism, socialism embraces marxism and many other theories, mainly economic. Socialism can be compared to capitalism, you can also get multiple ways of goverment under this economical system. Aproximative examples:

Capitalism as economic order, one way of democracy (because there are also several ways of making democracy) as political = Most western countries

Capitalism as economic order, fascism as political = Spain during Franco.

Socialism as economic, democracy as political = Chile with Allende, Spain in the 1930s. Yes, I am aware they also skipped democratic laws, I am talking about theories.

Socialism as economic, totalitarism as political = Most so called "communist" countries, wich are a perfect excuse to badmouth Marx: Soviet Union, China, Korea, Cuba...Cuba being the lest totalitarist, but still far from democracy.

Capitalism as economic order, anarchism as political = What that test defines as "anarchism", which is not. It's anarcocapitalism. Like...Midgar in Final Fantasy VII. Also, calling this "anarchism" is somehow a contradiction, as a-kratos y lack of power, and anarcocapitalism would have people in power.

Socialism as economic, anarchism as political = Basically what Marx called "communism" or "the end of history".

Basically, the test is stupid. Very stupid.


And here is a more serious one:

I wont do it again, but the result I had was the bottom left corner, a lot to the left, a lot to the bottom.
