Of course, everyone is entitled to have their own opinions, especially on fiction. But why do we always have isekai stories, for examples, with dragons being slain - while demons, about who there are also a lot of legends of heroes defeating them, becoming main protagonists - and even becoming dragonslayers sometimes?
It is unfair that while one popular fictional specie gets being slain an another one, in the lore about hunting non-humans down, become major protagonists.

P.S.: I do not hate demons, I love Demonslayer (some demons are good guys in it) and Beelzebub series.
