Your view isn't their view
Of course I'm not saying that Religious Trauma isn't a thing, but I'm taking her words with a grain of salt (but because I'm skeptical after seeing too many people on the internet lie or over-exaggerate their experiences to gain sympathy-cards, which leads actual victims to not have the courage to speak up). Of course, I cannot prove it, so don't take my words as 100% factual.
Let's give her the benefit of the doubt.
In her case, is basically going to an extreme to another. Eve is a victim? Good, we can all think that. But why shifting all on Adam, who he's also a victim? Why cuddling the one (Lucifer) who actually caused people to sin and portray him as a one-dimensional good boi?
It's not like I don't understand why she wants to make Heaven the bad guys and making it a criticism on dogma, but the fact that celestial beings don't even know their own rules, are not super strict and basically only Adam and Lute were the problem, is very telling if you ask me.
Not to mention her showing believers as one-note fanatics.
And not even interesting ones like Judge Frollo
Sure, she does say that it all fictional, but for the way she wrote actual biblical characters, it looks bitter, like she's shouting "look mom! I'm edgy!"
It looks way too much like her own singular view rather than a much more explored one.
Is not like putting personal views is wrong, but it can be alienating when you do not even try to elaborate the view you're showing up.
Plus, as I mentioned before, it doesn't make sense that she wants to make it a criticism to this specific experience when in the show it's not even brought up actually (the Seraphims are women, Adam is submissive to them and his army is only women, Lucifer is spoiled in the story along with many other male characters)
Adam doesn't work as a portrayal of a religious fanatic simply because
He's not self-righteous, he openly says how much he loves killing sinners (just like Stella says to Stolas "I love hurting you because it's fun" and we're supposed to take her being abusive seriously) so he's not finding an excuse to his bad actions.
The angels created him and apparently in this version he didn't ate the apple, so why would he be an awful person since he was "born"?
He has physical and verbal contact with Sera and other beings from Heaven, so you cannot even think that he's a crazy guy with a twisted view of the Bible. (Has any religious fanatic actually talked to God? Is there a proof about it?)
From her perspective Adam may appear as the kind of people she met who told her that women should stay in their place because of Eve, but from the execution, it gives the audience he feeling that he's just a jerk who have good points on sinners. In fact, one of the main issues is that Adam's misogyny feels irrelevant or, even worse, not actually present (as I mentioned before, his army is full of women and he's submissive to the Seraphims who are also women). What does his misogyny even have anything to do with the genocide of the sinners? Because he's not like he's targeting female sinners specifically.
It's kind of ironic that Adam from Paradise Lost (a book written by a puritan by the way), after eating the apple, appears as a much more perfect representation of what Vivziepop probably had in mind. Once he sins to stay with Eve, things go from bad to worse as he starts to blame her for what happened or even blame God himself by saying that if Eve was perfect before eating the apple then she shouldn't have eaten it in the first place.
This is why Vivziepop should have put Sera as the main villain and elaborate the two ideals (the one from Hell and the one from Heaven) to give the audience the conclusion that Heaven is in the wrong.
