This website is biased, it most likely randomly generates your stuff.
It couldn't be random if it was biased.
And in addition to what RedGajin said; You don't have to be Riddler or Stalin to have communistic tendencies in your political stances. This website is going by the textbook definition of communism and what it really stands for, they're not calling you Kim Jong-il. The definition of communism is:
Communism is a sociopolitical movement that aims for a classless and stateless society structured upon common ownership of the means of production, free access to articles of consumption, and the end of wage labour and private property in the means of production and real estate.
Communism isn't a bad thing at all actually, if it were executed properly it'd be a perfect system, however it's the way it's exploited by power hungry people that's bad.
