>>116735927There's very little socialism in the series and the closest it gets to that is Amon and Kuvira. Hell, Amon's posters in the series look just like Stalin's.
The series itself border libertarianism much more often with its focus on individuality and freedom. I'm looking at you, Zaheer, Zaofu city, Republic City, Korra, president Raiko, entrepreneur Varrick, soon-to-terminate-monarchy king Wu.
