If it's about associating queer fans with toxicity then the st8 ppl have a lot more to worry about with all the shit they do. And the shipping goes both ways. Straight people also try to explain queer characters straight even if they have to go through like 7 stages of mental gymnastics. And these manhwas are fictional, by shipping characters here they're not really harming anyone. In the case of shipping fictional characters not associated with real people, it really is harmless fun. People enjoy their fictional medias in different ways. Although I'm not a shipper I wouldn't say it's doing any harm to the queer comm. Like the st8 ppl need to suck it up if they're bothered by someone shipping 2 fictional characters.

June 2nd and we’re still dealing with this! Shipping delulu isn’t just “harmless fun”, it actually hurts the gay community in so many ways, and here’s exactly why:
It erases and neglects actual queer representation: You pour all your energy into shipping straight characters or platonic friends, while completely ignoring or sidelining canon gay characters and confirmed queer relationships. Those genuine representations are already rare, and instead of supporting them, you give all the attention to made-up ships, this makes it harder for proper LGBTQ+ stories and characters to get the visibility and appreciation they truly deserve.
It reduces queer identity to a mere fantasy or headcanon: By forcing romantic or gay dynamics onto characters who are explicitly straight or just friends, you treat queerness like something you just imagine for fun, rather than a real, legitimate identity and relationship type. This makes actual queer people and their experiences feel invalid, trivial, or like they’re just a “toy” for your entertainment.
It spreads hate and hostility toward the gay community: Because people force ships onto straight characters or friendships, people start associating queer fans with toxicity, and it creates a negative image of the whole community just because of these shippers. We end up getting blamed or hated for things we didn’t even do. When we just want canon stuff and not delulu
