In essence I suppose I don't understand stanning. I might have a pfp of an idol but that's a novelty. I am not actually keeping up with the artist on a regular or even listening to all of their music without fail. But kpop stans are super loyal to their favourite groups, going as far as to listen to everything their faves release whether they like it or not. Sometimes I might like only one or two members of the group.
Another aspect of this is the company stanning. People might think I am a Red Velvet stan (I am not) and expect me to defend SM but I would be the first one to say that SM lifts off black artists and has a history of treating their artists horribly. Yet you've got kpop stans literally defending these companies as if the company is their faves.
Is the concept casual listening alien to kpop these days?
