This is something I've noticed in the Kpop stan community. People and users very SERIOUSLY believe they and their faves are SUPERIOR TO OTHER FANS AND GROUPS.
When I say I'm a GG supremacist, I'm joking around. I don't LITERALLY THINK GGS ARE BETTER THAN BGS OR THAT BGS ARE TRASH. But, there are users who seriously think and act this way. GG stans dismiss and look down on bg groups/stans, and vice versa.
People never seem to remember selfmate wise saying DIFFERENT STROKES FOR DIFFERENT FOLKS.
No group, no matter how much you like them, is SUPERIOR OR BETTER THAN ANOTHER GROUP OR FANDOM. You aren't a better person for staining a nugu, or for stanning a big4 group or GG or BG or Soloist or idol who produces. Who you stan, shouldn't define you and make you act like you're better than other fans.
We're all stans here. No group is actually trash or untalented. Kpop is an industry full of talent, so no group of fandom is superior to another. Don't talk down or disparage fans for who they stan-- that's just rude and a superiority complex.
