I don't like this genre, and still find the intentions of authors making such stories suspect.
The authors are largely motivated by their editor's propositions. Their editor/publisher is motivated by profit potential according to some brand for whatever publication they're managing. Accordingly, they're responding to consumer demand.
In my observation, the consumers of this material are virtually entirely normal (or, as normal as you would consider a garden-variety otaku-type pervert, as opposed to a potential criminal), and their interest in the genre usually comes down to it being a hyperbolic expression of female domination alongside the typical attraction to an attractively drawn female character (you're very liable to hear some variation of "god I wish that were me" from them, to demonstrate this). Where the executed dynamic grants the younger party domination over the older party, the fascination is with the
irony of such a scenario. And all of this is about completely fictional material, whose imports are rather easy to compartmentalize and/or discard.
Their fixations are otherwise unremarkable or aggressively eccentric. They may even just be trying to be the most "exemplary" in internet communities built around that trope, with no serious interest in it.
I don't get why you're so passionate about this though.
I'm not so passionate that I can't recognize the possibility that someone honestly didn't know what this story was going to be about before deciding to read it, nor am I so passionate that I have a problem with people disliking the premise. Honestly, this chapter was hard for me to look at head-on, and if it's going to continue to be that absurd and one-note, I'm likely to drop it.
My annoyance is with unfunny performative moralism and Jack Thompson-tier arguments that certainly aren't being consistently applied across all media, and much more so when these types deliberately consume media that-- either before or very early on-- they know they won't like, and
then go on to publicly declare that they consumed said media and consider it liable to engender grave moral ills. It immediately calls into question the motives of said person, since they willingly consumed it themselves.
At any rate, I've become convinced that these people aren't earnestly speaking about positions they've thought out, rather than regurgitating lines for speaking's (and memeing's) sake. Despite any alarmism, the way they talk and act about the material betrays their indifference.
