It sounds like you're referring to a book? Maybe you can clarify. I read Capital Vol 1 during COVID, and I've come to realize that, without being hyperbolic, I've encountered zero people with criticisms of Marx who have read what he's written.
It's commenting without reading the article on steroids and it frankly makes the critic look foolish because they fantasize about the books content and then attack their own fantasy and then claim they haven't done so. It's not difficult to read a book and then critique it. It's just wild that this had repeatedly failed to occur.
People don't seem capable of reading things they might disagree with, and seem unable to accept that anyone might write something that has parts that are right and parts that are wrong.
Psychs call this all or nothing approach, black and white thinking or splitting and it's a defense mechanism. I think we can do better.
There's a very simple way to prove my statement wrong by contrary evidence. Someone can simply read a book they might disagree with. I actively encourage it. If someone has the desire to voice their disagreement of a thing, the least they could do is be familiar enough with the thing to make a well-constructed and relevant critique. I actively encourage folks to be better critics.
