My least favorite thing about damijon/jondami is that...it tends to lean into a lot of typical shota tropes? Especially regarding Jon, and it honestly creeps me out. It's so weird. I was looking through my old Ao3 bookmarks, and it becomes so obvious not only how OOC Jon always is but just how much he's simultaneously infantilized and adultified (is that the right word?) in fics that want to make him have this weirdly kiddish crush on Damian while also making him super possessive.
Just an example: It's very very common in these kinds of fanfictions to have the trope where Jonathan loudly proclaims he's gonna marry Damian when he's older and then Jonathan continues to "pursue" Damian, making him promise to "wait" for him (which Damian agrees to?? For some reason??) up until he's 18 (and Damian is TWENTY ONE) and then Damian "relents" and agrees to date him.
Or I've seen ones where after Jonathans extremely traumatic time in the volcano he...tells Damian they're old enough to date now??? LIke I vividly remember this happening way too many times. And there's more examples, like scenarios where Damian dates a girl because yk, he's a teenager, and Jonathan gets extremely jealous and threatens her?? Not to mention when they just make Jon straight up stupid because "that's how kids are".
Jon is made into Damian's lap dog in the worst way (quite literally at times where they turn him into basically Damian's guard dog and call him as such). And I can't help making these comparisons, especially now that I can recognize these tropes.
ALSO. THE WAY THEY ALWAYS TREAT JAY LIKE SHIT. I have unironically seen fics where they say the only reason Jonathan is with Jay is because he "looks like Damian"...because they're both asian. Like that is the exact justification they have given (in different words but essentially the same thing). Jay is turned into this jealous ex/scorned mistress where all people know is that he's a journalist and not the fact he's the son of a president and a victim of human trafficking.
My least favorite aspect of this trope is whenever Jonathan date Jay--whether this is after a confession, post damijon break-up, or hell, just happens to be dating AT ALL even if neither Damian or Jonathan gave any indication to the other that they have any interest in them-- Jonathan is made out to be some kind of bad-guy by both the narrative and the batfam.
You have Jason threatening to shoot Jonathan with kryptonite bullets, Bruce refusing him into Gotham, Cassandra threatening him in the middle of the night etc. All because. Jonathan. Chose. Not to date a child. Because to be clear, that is what has to be happening if there is any preservation of the timeline at all. Jonathan has to be around 17-19 and post age-up, and Damian can't be older 16, if that.
Also another trope I hate that I'm adding to the end here because I remembered it against my will. Jay using Jonathan so he can get information on the Waynes to "further his dreams in journalism". That is so incredibly moronic and genuinely disrespectful. They know nothing of why Jay wants to be a journalist or even what kind of journalism he does.
For any author who reads this and wants to use any of these tropes with Jay , just use an OC. Don't disrespect an activist and victim by turning him into a gossip chaser.
