Marxism Is Useless (And Somewhat Dangerous) As a Critical Lense

Marxism is occasionally used as a lens with which to view fiction through, typically as a method of viewing class-struggle. But that's not necessary. One need not adopt the failed ideology of easily the worst regime of the last century to analyze a work from the perspective of a class struggle. That's like adopting a lens of Nazism for the same purpose, it's unnecessary, somewhat dangerous and ultimately pointless, as one need not take a COMMUNIST approach to a work to analyze something from the perspective of a class struggle. Class-struggle is not, and should not be exclusive to a Marxist reading of the work. To allow Marxism to dominate economic struggle and class struggle is unhelpful and somewhat dangerous. Again, it's equivalent to using Nazism for the same thing. Hell, it might be worse, as Nazis are far less likely to elicit a sympathetic response than their Russian brothers are. Somehow the Communists managed to convince the world they weren't as bad as the Nazis when they were objectively worse, and with as bad as the Nazis were, that's saying something!
Adopting Marxism as a critical lens normalizes viewing aspects of the world through the lens of one of the most dangerous and harmful ideologies the world has ever known. I cannot imagine how or why any right-minded human-being would even suggest such a thing. Critics need to broaden their viewpoints and realize that when they restrict themselves to critical lenses they ultimately cannot get a true view of the work. Indeed, no lens can give the whole truth about any work on its own, especially when one is not working with the correct terminology. In fact, one need not even use a specific lens to gain a full view of the work. Repeated readings of a book or viewings of a movie can unearth hidden themes that not even the creators know about, and a creative mind on the part of the critic can unearth far more than any lense possibly could. That's not to say that one cannot get any benefit out of a work when specifically searching for a given theme, but that it is far less useful than a less-specific, broadminded view of the work. When looking for themes, one may conjure up a theme that the work doesn't lend itself to in even the broadest of readings, as opposed to a less specific reading, which will likely put a better image of the messages conveyed to the average reader in one's mind. Looking at a work through a lens does not lend itself to anywhere near a realistic reading of the work, much in the way that going through one's life looking through binoculars does not lend itself to a realistic view of the world. The best lens to view anything through is no lens at all, entirely because one's viewpoint is not tainted. For instance, going into the movie Ender's Game looking for an anti-homosexual agenda is entirely pointless. No such themes exist in the movie, intended or otherwise, and all that lens does is diminish one's enjoyment of the film.
