its not that serious

?

I don't watch much anime, but how many animes with dragon slaying are there really? Dragons are often seen as noble and majestic creatures in Eastern cultures, the dragon in Shang Chi and the Ten Rings was the force for good for example.

Dungeon Meshi.
Sosou no Frieren.
Drifting Dragons.
Ragna Crimson.

Being nice guys does not guarantee dragons staying alive.

I just feel people started to hate dragon characters recently...

Out of all the anime that exists, that's not very many. I have seen Dungeon Meshi, and the dragon there isn't even a true dragon, just a glorified guard dog constructed out of blood magic by the mad mage.

I wouldn't say people hate dragons, though. Dragons are one of the most beloved fantasy creatures in all of fiction, they're iconic. They just make easy villains because of their nature to hoard and steal treasure. In fact, dragons have appeared in stories across various cultures from the Vikings to Feudal Japan going back centuries.

There are more, I just mentioned recent ones. Well still it looks like a dragon and it was, what is the worst in its death, consumed.

As I said, dragons don't need to be evil to be slain and I gave you an example. But the another problem is that such dragons are blank characters - no motivation, no personality, just appear and die. And not necessarily because a dragon is evil.

Dragons have been depicted as dangerous animals for centuries in Western fiction. Them being intelligent creatures capable of speech or magic is a more recent 20th-century invention. I can at least applaud Dungeon Meshi for showing the characters using the dragon's carcass for its meat instead of just killing it for glory and sport like so many other depictions.

Getting upset and complaining about the way dragons have been depicted in fiction for most of human storytelling won't change anything. If you want to change how dragons are depicted, you need to write a fantasy novel or a manga that challenges the fictional norms of dragons, making them more complex and interesting than just flying lizards that breathe fire.

Like what Skyrim did by giving them history, culture, written language, the ability to talk, etc. Dragons won't just stop being fantastical beasts for heroes to slay over night, that's a fictional trope that has remained largely unchallenged since the 8th century.

Yes, I know. But the problem is that, at the Year of a Dragon, we have an overhyped anime series featuring a dragonslaying. Moreover, a dragon has no personality and no motivation other, than being just an animal who eats humans. Furthermore, it becomes a dinner itself. A f*cking dragon, a creature who should be at the highest point of food chain!

Well I do not complain about dragonslaying legends such as St. George or Sigurd. They are ancient and they can be countered by legends from Far East and Central America. I talk about modern series only.
The problem is that there is a big lack of good dragon lore. Alive dragons either don't resemble dragons, or they serve as pets, or they are forever locked in human bodies without any chance to transform back.
Also there is much less dragon merch, except for Toothless since he is cute as heck.

Well Skyrim is an another case and dragonslaying trope here can be countered by the fact that at least 2 of dragons do not die. I mean dragonslaying is ok only if:
1. A slain dragon is an actual villain and it is bad as f*ck (Deathwing, Acnologia, Alduin etc. No, they don't kidnapp damsels (Deathwing is married btw, his wife is a scientist), they don't burn villages down - they want to destroy the entire world instead. That's what a villain dragon should be).
2. There is something to counter it with (WoW as an example, where there are several dragonslaying case - while there are 100500 dragons existing within the game and we have even got a Black Dragondlight redemption arc in the recent DLCs).
3. A dragonslaying is an act of helping an another dragon (One Piece, but it is questionable since Kaido's fate is unknown).
4. A dragon is killed by an another dragon or by a half-dragon or by a dragon using a human form (to show a power difference, that one of dragons is so stronger that it can kill an another dragon without even using its dragon form). Sekai no Owari Encore as an example, where a dragon supporting protagonist one-shots one of her kind for stalking her without transforming (though her dragon form is ... pretty weird).

Slays a wyvern, eats it for a dinner.

A main character's future father-in-law and brother-in-law.

Yes, both anime series got anime series. But the problem is that dragonslaying series such as Dungeon Meshi or Sosou no Frieren do apply to anime fans more. While both mentioned series are highly criticized.

An example when it is ok.

A main character slays a dragon at the very beginning of a manga within less than 30 seconds.

Well now, without opening a link first, guess what differs one of a main character's girls (a main character's very first student and team member before he isekaied, btw) from other members of a team.

An another example of a "good" (not) treatment of good dragons.

HE WAS SLAIN OFFSCREEN!!!

That's how modern anime/manga/manhwa ec. writters treat dragons! Good dragon? No, let's have it being slain for drama!
That's a hate!
