Generally true, yes. In most cases, the leftists using that sort of terminology are tankies, meaning they are explicitly pro-authoritarian. They just want the dictators to be communists (or claimed communists) rather than capitalists (despite said dictatorial communism usually being about seizing all the money for themselves anyways and often results in full on capitalism regardless, China is a great example).

So you don't even need the word replacement thought experiment. Tankies are openly authoritarian.

I have a friend who has come to reflect this exact behavior to an extraordinary degree of accuracy.

It's interesting because the near puritanical nature of their responses to nearly anything has become more extreme than even the most devoutly religions individuals. Obviously the focus of their evangelizing is very different, but it has become difficult to even have a conversation.

I'll give you an example: I saw a new game called Pal World, which looked absurd, mentioned and was instantly met with the fact that the game was unacceptable because it supports forced labor.

Additionally, there seems to be an immense amount of hypocrisy in regards to what is good and what is bad, largely driven by what best I can refer to as their "leftist Zeitgeist." As bad as I can tell now, according to them, I am a liberal, and apparently liberals are bad, and the only true salvation is being a leftist?

Of course, I have a much more varied and complex set of moral and political values that likely don't fall under a singular label... But what do I know about anything.

Outside of the word "capitalist," literally nothing presented in the top half of the image is even political, let alone authoritarian 🙄 it kinda seems like you're just using popular negative words against things you dislike.

Marxism and Christianity only share the fact that they contain frameworks for analyzing material reality(Marxism through Materialism and Christianity through representing reality as though it is divine, and thus explainable via the divine), and this post seems to not be willing to honestly engage with Marxism as a concept.

1. Marxists do not oppose incremental change. Marxists believe that minor concessions under Capitalism are insufficient to actually fix the underlying problems, and this point of view is built on a thorough understanding of the Marxist critique of Capitalism.

2. Marxists do not oppose reform, they just believe it is impossible to do successfully without sliding backward, because the state is built in a manner that supports Capitalism and resists change.

3. Marxism is an economic critique of Capitalism, a philosophical framework, and a call to action. It is a complete set of tools to look at the world, analyze it, and how to fix it. In this manner, it can be superficially compared to Christianity, but only on the surface.

That's really it.
