You see, boys and girls
Are children your audience?
Modern Art -- just like much of Modern Music, Modern Literature, Modern Science etc.
It's impossible to compare modern art to modern science, false equivalence. One is artistic human expression, the other is an attempt to discover and understand the world and reality.
distorts and perverts the appreciation and understanding of the good, the true and the beautiful.
You use beautiful a few times, claiming that it strangely has to do with a specific moral code. I could point at many instances where the beauty of the world can no longer be perceived because of fatalism and religious indoctrination. Also, to many scientists, science has exposed the world's beauty even more than ancient humans had ever access to. There is no reason for knowledge about the world to not also be able to evoke human emotions and awe.
black is white, crap is gold, gold is crap, men are women, women are men, etc, and soon you can sell these "educated" chumps anything.
So this clearly exposes the motive. You have an ideological view of the world to preach and must misrepresent anything that competes with it. Yet many things will, considering that it's ideological and wants to impose reality, rather than discover or study it.
From there, the madness will eventually flow downhill to "the masses." There is no right and wrong for truth, like Einstein's "curved universe" (rolling eyes) and his "time warps" (rolling eyes) is all about "relativity."
Here again, there are less reasons for knowledge about the natural world to promote mental illness than ideological indoctrination. Not only holding unrealistic views in a stubborn way is a source of constant deception and conflict, but some doctrines are not very different than some psychotic delusions, except that not all believers are "mad". As someone else noticed before me, you're also confusing a scientific theory with moral philosophy. So far, relativity provides a better explanation for some of the scientific observations and much of its hypotheses have already been tested to be accurate (a few other implications may never be able to be fully verified). Then it's unclear if you also reject physics, but "rolls eyes" indicates that possibly. If so, you're denying some of the most established knowledge and working hard science.
suppress one's own God-given instincts, and then choose to believe in nothing, unless the "powers that be" (cough cough) instruct and authorize you to believe in something, that is.
If you are still mixing up science and ideology here, you have to first show evidence that human instincts are "God-given". In a scientific perspective, "believe nothing" can apply in the sense that conclusions must be derived from knowledge, but hypotheses can certainly be considered a form of belief, advancing propositions made by inference, to be tested. Then your "powers that be" would be confusing working knowledge and scientific theories with authoritarianism, also a false equivalence. But since you're confusing knowledge with art and religion, it's not too surprising. Ethics can be informed by science, the same for law codes, although both can also be based on ideology, or take in consideration other factors of human existence and society.
The protagonist these days is typically a mentally conflicted hybrid weirdo
You appear to be dismissing as "mentally conflicted" and "hybrid weirdo" what does not fit your irrational ideals. However, characters in entertainment are rarely designed to portray reality, at the same time they often are presented as flawed and naive so that the audience can somewhat identify with them and appreciate a certain level of character development.
truth is only a point-of-view which aimlessly drifts with the polluted tide of "popular opinion"
Still confusing ideology, opinions and facts, as well as religion, art and science. Fringe proponents commonly call their beliefs "unpopular opinions", but many of them are simply false and can be described in more accurate terms.
manufactured dogma
All dogma is manufactured dogma, including yours...
mass psychosis engineered by the usual suspects
Repetitive, but here again, this is projection and your "usual suspects" suggests a conspiracy theory.
Heck! Even the Poop Francis of the "modern Vatican" refuses to call sin by its rightful name.
Yes, religion and sectarianism are both a product and a source of conflict.
Although the Argentinean ass-clown did indeed pass very strong judgements against Global Warming ™ and xenophobia ™, but we digress.
Well, it's nice when some religious leaders at least acknowledge reality up to some point.
a people that can no longer distinguish truth and beauty from falsehood and ugliness
Climate change denial and other science denial, including pseudoscientific creationism, is indeed propaganda intended to confuse you and make you forget that some opinions are more valid than others for verifiable reasons.
all manner of political deception, oppression and enslavement.
This reminds me of what happens in US red states. The subjugation of women, keeping people poor and desperate and in an atmosphere of fear. Discouraging education and manipulating them including for corporate and political purposes. Exploiting them as an easy source of underpaid workers and soldiers...
