One thing i've noticed in general is people are very aware of illuminati concepts but people will still eat it up and just accept it like this is normal, the hand signs, poses, darker themes. Backlash for performers (performer not idol) is for social issues, controversial remarks or attitude but satanic concepts are fine!?
"They're in their illuminati era lol" (from a fan account that will continue to post about their favs)
K Pop has become huge and very influential over the last decade, I predict it'll fade away over time and a new industry or genre will be the buzz, again this will take time. BTS and many other bigger groups like BP have fallen off..the industry is steady but we've past the peak.
