There was a point about how claiming that BTS isn’t K-pop will further the stereotype that the West perpetuates about K-pop.
However, the history of popular music in the West shows us that dismantling the “boxes” that keep POC artists separate is a more effective way of integrating musical styles/cultures into the mainstream. This helps eliminate preconceived notions and biases associated with certain music styles. For example, hip-hop was heavily stereotyped in its early days and was never expected to last beyond a few years, but as it began to make its way outside of the “other” category it was placed in, it began to spread across the globe and has since turned into one of the most popular genres in the world. There is certainly a difference in claiming that BTS is better than K-pop versus BTS is different from K-pop. The former might perpetuate the stereotype of K-pop, but the latter allows both to be understood and recognized more critically (without generalizations). It forces people to discuss elements of Korean music and culture, and it challenges the flawed Western assumption that all Korean music is K-pop.
“Are there opinions expressed that are potentially the result of misinformation? If yes, what?”
From my understanding, no!
