I've been a big listener to Kpop since 2012. I've found so many groups to be unique, original, master piece choreography, vocals on point, but also fandoms out of control. I have a long list of groups I stan, but the biggest has to be Girl's Generation. I've loved them since I heard "I Got a Boy" and I will never let that song die on my playlist.
I love each band individually and I choose not to compare one to another, like Ateez to BTS or Mamamoo to TWICE, so on and so forth. Each band gives something new and fun, whether it's lyrics, choreography, a funny member, a new home, a friend, whatever it may be; KPOP is for anybody and if people don't like it, well that's just fine. I just don't think people need to hate it ferociously, I don't mind some music but I don't explicitly "hate" country and won't listen to it constantly because it isn't my taste. But I would never ridicule somebody for liking that genre or anything like that.
Fandoms on the other hand, some definitely get out of control. I'm a Blink and an Army and, yes, we coexist. Because I love both bands, I don't like how YG is producing BP and other reasons too, but I still have a soft spot for those girls (I personally loved Kill this Love tbh). I listen to both, I stan both, I love learning new things about both. But no, I don't think one is better than the other or any other group, "they don't deserve the fame" yes they all do, it's their dream.
Closing statement: Kpop is wonderful if it's for you, I say give it a listen if you'd like, but I will forever enjoy the music.
