A friend at work is into KPop a lot. So when BTS started coming into my radar, I asked her all about kpop, the terms, the system, etc. Fortunately she mentioned early on that she hates BTS so I tried to not asked her directly about bangtan, only kpop in general and other groups she faves.
After she was sure that I wasn't into BTS, she confessed that the reason she hates BTS because they're copying other groups. For example, she hates that BTS is glorified as the group who uses socmed heavily as if BTS is the pioneer while according to her it was other bg who invented the method.
Well, it's not a wrong fact. But in my opinion, everyone copies someone. It's a matter who uses it better. I was tempted to tell her that even her fave bg is copying Seo Taiji and Boys.
Anyway, other than a BTS-anti, she's a nice girl, we get along well.
I suspect her anti was triggered by many articles out there that blantantly wrote about BTS in excessive flattery.
