how exactly do they think this is going to play out?

Teacher: Communism is bad because Stalin killed people.

Student: So all Stalin had to do was not kill people and communism would have worked?

Teacher: No, the ideology made Stalin kill people.

Student: So Stalin did not have free will?

Teacher: No, free will exists, don’t be a dirty Calvinist, Stalin was willingly following Marx’s ideology to the letter.

Student: So how did the ideology create the regularly recurring famines that happened for centuries until the 50s, cause the kulaks to burn their own food, or the Western powers to sanction the USSR before the USSR had done anything wrong? What part of Marx’s writings caused this?

Teacher: I’m legally required to report all dissenters to the Department of Freedom.
