Let’s start with it’s none of our business if a person stan zero, one or 12829929192 groups.
I don’t know if for you guys think the same but for me stanning is not only listening to 2 albums and know the members names, I’m a casual listener of so many artist but my stan list is very short. I guess everybody have their own concept of “stanning” but I have known people that preach to stan someone and don’t support their music or even mention them.
Why would you say you are a stan of certain artist if you don’t even really have an interest. If you just like some songs is fine just because of that you don’t to say “I’m a [insert fandom name]”.
For the people that stan only one group is so weird to see some people (multis) trying to shame them and viceversa too. Some people just don’t really like that the concept of stanning multiples groups and that’s fine because they can still listen to the music of other groups.
Isn’t like the people that stan one group only listen to that group don’t be dumb.
