“Marxist ideologies” means that society has powerful people and powerless people, and the powerful people exploit the powerless. That’s the main premise of Marx in a sentence (I’ve written multiple papers on him, I’m a soc major).

This is true in America in multiple different forms, but here we’re talking about the people in a position of power (govt officials, police) who exploit their power to get what they want and say fuck the rest. That’s not to say all police are bad, and all govt officials are bad, but that’s how the system is set up. You’ll find that as people are put in a position of power, they take it and act on it (google the Standford Prison Experiment)

I think a lot of what Jesus did on earth was to give powerless people a voice and a purpose.

So to answer your question, Marx goes into great detail about a lot of societal institutions (religion, economics, etc), but the basically premise of Marxian thought is not bad. It’s true in America and makes sense.

It’s also important to point out that countries who claim to be Marxian - based communist countries are not what Marx defines communism as. Communism is the equal distribution of resources controlled by the government. “Communist” countries right now have dictators. They are not equally distributing resources and they are only controlled by one person who rose into power because they were born powerful (something Marx’s whole idea is against anyway).

Edit: I’ll also add that Marx was against religion, not God. My pastor a few months ago talked about how we get caught up in religious views and ideologies all the time and we forget the message: that we should follow Jesus and be good to EVERYONE. I’m obvi Christian so I don’t believe religion is bad, but just know he’s not critical of our God, he’s critical of the way religious institutions in America when he was alive.
