I don't stan kpop I stan bts

I really used to love James Corden alot, he had a lot of respect in my heart until he called us 15 years old girls, seriously, this stereotype about the ARMY fandom needs to be cleared, the teenagers are just a majority of the fandom there are people who are above 70 , who love BTS, if only 15 years old girls love BTS, then how come they sold out the whole Wembley Stadium if only 15 years old girls stan them, also big celebrities of the Western Music industry also love BTS such as Cardi B, Taylor Swift, Halsey, Megan Thee Stallion, Justin Bieber, Drake, Charlie Puth, and many more, and by their age or facial characters they don't seem to look like 15 years old girls, and even John Cena and he isn't a 15 years old girl, is he?
