I was thinking about how these freaks tend to be shitty writer and came up with some explanations. Sorry for making it TL;DR
-Their stories tend to be more simplistic, bland and less creative because they refuse to write anything that can violate their ideology as they are pathologically obsessive with it due to extremism. Diversity hire bullshit which includes extremist staff pandering was also suggested as a reason due to the poor staff quality that results from this practice.
-They love shoving their extremist ideology into everything, which is why several of their stories contain negative depictions of whites and men, with the nature of said depictions being comparable to a neo-nazi's depiction of Jews. They also tend to be full of other themes designed to pander to their kind as well as references to their conspiracy theories that are depicted as if they are all true. An example of this would be the infamous Mafia III, which contains several instances of regressive leftist themes and a reference to the regressive left's "alt-right" conspiracy theory in the form of a Klan like org known as the southern union, which it's leader denies on their radio show.
-They're prone to making Mary Sues and turning preexisting characters into them like in the case of Marvel character Carol Danvers, which was so disastrous that people now mix up the character's name with the joke nickname Carl Manvers. This is because they think that depicting a character who's supposed to be "diverse" with any real flaws violates their ideology, and they have responded to the criticism of their characters being Mary Sues by declaring the term to be hate speech.
-Their pathological extremism often distracts them from proper writing, resulting in writing issues such as the fact that it was never really explained how in the sequel trilogy that some imperial warlord in the outer rim was able to successfully build a massive planet integrated death star successor that is powerful enough to obliterate multiple planets rather than something more realistically powerful lore-wise for their factions size, and intimidate at least half the galaxy into surrendering to their rule while somehow being able to establish and keep that rule when said superweapon got destroyed in a small time frame after it's first firing.
If there are any other notable issues or corrections you may have then feel free to suggest them
PS: I think it would be funny if someone turned against the regressive left because they got falsely declared a troll and wrongfully banned from some community for calling Carol Danvers Carl Manvers by mistake, just because of the joke nickname's popularity among the anti-regressive movement.
The left also hates flawed characters or stories that have "unsettling elements" because it could potentially "normalize" it in their eyes and readers will associate with it.
For example: according to a leftist if a character makes a remark about gays in the book or a joke, that character must immediately be questioned, shot down, or somehow made to see the errors of their way.
Or, if let's say you are writing a fantasy novel heavily based off the Roman Empire(hell, it could just be a fantasy novel based in the roman empire.) A leftist will tell you not to include any mention of slavery and if there is slavery in the world the MC must be opposed to the idea and that the simple existence of slavery means the novel's main focus has to be the abolition of slavery. They're so deranged to think if someone is reading a book where there is slavery that the readers will come to think that either slavery is ok or be completely unable to relate to anything that is modern society and won't read it.
I've seen the biggest push now is for trans MCs and how they should never be misgendered ever, even by villains who hate them because you need to show villains who might otherwise be murdering and torturing people have "basic human decency" and know it is never ok to misgender.
