I'm not understanding here... Aren't TS fans the ones dragging Adele? What kpop fans have to do with it?
OP might be saying that even though Western pop fans have terrible behavior online, Kpop fans have even worse reputation.
I think that Twitter in general is toxic when it comes to everything pop music. I wouldn't compare Western pop fans and Kpop fans. Both can be horrible.
Just yesterday NCTzens and ARMY were having a fanwar that trended on Twitter (#nctdisband was trending even in my country, it was a total mess). The situation behind it was very serious. It's not any better than Western pop fans if you ask me.
