Any excuse of Aggy using his comics/art to deal with his trauma goes right out the door the second the sexual content switches into a fetishizing gaze. From that point, you can see Aggy turning abuse into something positive and desirable. There are countless people who work through their trauma by incorporating it into fiction, and it's obvious from how the narrative is framed that there is no pleasure or glorification derived from being sexually assaulted, for example.
However, you look at Aggy's comics and he's reveling in everything that happens. The characters talk about being afraid and abused, but the framing suggests that reader is expected to almost "enjoy" the results of the main character being abused. When the abusive mother scenes are over, there isn't an overwhelming sense of a despair from the main character, just the abuse leading immediately to a sexual pleasure. Pages 16 through 18 illustrate this the best, I believe. Page 16 isn't illustrating the desperation or confusion the main character is feeling, it's framed in a purely sexual way. Every panel is sex for sex's sake in a way that is distinct from the other pages (that are still fucking disgusting, don't get me wrong).
I could be off, though, but it's a feeling I get.
That's why I'm just instantly disgusted at anyone talking like this. It's almost always a signifier of something disgusting like they're diaper shitters or worse.
I remember reading somewhere that this type of "baby talk" is nothing like how actual children talk, not just on the face level of turning every "r" into a "w," but where they go and how very young children structure sentences aren't similar. I'm trying to find the source, but I'm having difficulty finding the right search terms.
Pedos and company love to use this exaggerated baby talk and it's just another way to spot a pedo a mile away.
