This is unbelievably true, and has been since the inception of this ideology. Now the ones who wield it call themselves Woke Left, but it's the same playbook. They use naïve useful idiots who think they're doing good because the script of lies they're taught always sounds amazing and is easy to recite.
If you look deeper into it, you'll see that this problem is not limited to marxism and predates it.
I think it's rather a type of person.
Narcissists do take great advantage of marxism as a useful tool to achieve their goals.
But so they do with conservative religions and all kinds of ideologies.
Look into flatearthism, for example. Full of narcissists taking advantage of others. Full of lies and deception. And they hate marxism.
Yes. But flatearthers are too absurd to go mainstream.
Do you think vaccines are less absurd?
Same level of coherence and "science", they used to be taboo and now they force half the world to inject their children with poison as soon as they're born.
Anything can go mainstream. Flat Earth going mainstream is the theme of the movie Interstellar, and I think it's not too far fetched.
