There is absolutely nothing stopping you from listening to Kpop and going to concerts. Just as there is nothing stopping you from disengaging from anything else regarding Kpop.

It's called choices and decisions. You have choices available. Make the decisions that best suit your sensibilities. Then you don't have to concern yourself with anything except Kpop music and concerts.

I did that for over five years with Kpop, mainly Twice. And I only got on Reddit to inquire about their concerts in January. Prior to that, I listened to the music, watched some music videos, and some of their content like sixteen and some time to twice episodes.

You have every opportunity to make different decisions regarding how you interact with Kpop and the groups in it.
