It’s kinda weird to have tons of huge portraits of just 1 person instead of art celebrating the masses or many different people or whatever.
I understand the impulse but now that we know enough to know that great man theory is a harmful way to think about events, how do we prevent large populations from falling into that hero worship mindset in future communist countries?
Cults of personality are a reactionary tendency of the peasant class in the revolution. They are generally illiterate, uneducated, and insulated from mass culture so they fall into traps like that. Once a country proletarianizes, such as in Cuba or China, the tendency disappears because the peasants become educated and socialized and they realized that they (their class) was more important to the revolution than their leaders.
In Cuba cult of personality is actually banned, people still created music and paintings about Fidel and Che.
