Don't get too down on art. There is a ton of insanely amazing art online if you just bother to look.
Browse through ArtStation or Behance and you will be blown away.
The future and potential of art is insane.

You make some great and nuanced points. I appreciate the serious effort.
However, from everything I understand, true communism and socialism will never work in our lifetimes because people are far too selfish and grossly underdeveloped.
But I think it could work 100+ years from now, especially if we start to modify our genetics and brains.
The problem is that no amount of reading Marx or whomever will address this root issue. My fundamental issue with Marxism is that it gets human psychology and spiritual development wrong, and therefore it becomes unviable in the real world.
If you have some points to rebutt my core issue, feel free to share them here. I am totally open to being proven wrong on this. Unfortunately I can't see a way you will wiggle you way out of the selfishness problem.
The benefit that capitalism has, despite all its flaws, is that it works. The same cannot be said for Marxism. There has never been a viable real-world, mass scale implementation of it. This should tell you something.
It is because of this that I advocate for social democracy. We know it works. It's hard to go wrong with it. And it is the next natural evolutionary step.
The bruden of proof is on the Marxist to show that Marxism can be viable in the real world. Show us that it works at the level of psychology and ego development. Explain why all the tried implementations failed.
The problem with reading old texts is that they do not factor in or explain all the failed implementations of Marxism. This is why reading Marx will not help. If Marx saw how Marxism was implemented over the last century he might reject Marxism himself.
The best moderm Marxist I know is Richard Wolff, and unfortunately I cam see flaws even in his rather modest ideas of democracy at the workplace and profit as exploitation. Although I generally support democracy at the workplace. But it is not clear how much democracy the current workplace can handle before it breaks down.

The New York Times has published an article that shows interesting things regarding a growing gender gap in political beliefs
Based on this survey it seems young people but especially women value diversity and inclusivity over freedom of speech. 

it’s important to note that the next generation of academics and thought leaders will likely be majority female. Women are now 59.5 percent of college students, and also more likely to graduate then men.
Could this attitude change how academics work and how knowledge is spread?

Social psychologist Jonathan Haidt reported on noticing a similar pattern when presenting at a private high school

Interestingly it seemed the boys were hesitant to give their opinion
Why is this? It’s possibly related to this explanation from the NYT article:
On one hand a stage green society should be more interested in diversity and inclusion and not offended minorities, however censorship support can sometimes be misused by those in power or lead to important information being hidden.

What are your thoughts on this? 

Pretty obvious result.
The feminine values communion more while the masculine values autonomy more.
Freedom and truth are rarely a woman's highest priorities.
