Because this person seems to be one of those jobless people that spend their entire life hanging around on the internet, hating others.
They will never get further in a career or reaching goals that way. Instead they get so twisted by what they read on the internet day in day out that their mind gets warped and unstable.
Tbh with you, i really find the nature of argument rather amusing, not one being written by a jobless, twisted or unstable person. I dont know the person and realistically never would in normal circumstances so I won't judge. I actually participated in this chat because yesterday I was informed by mods of this site that I need to reach 25 post to get my rights to post a thread and as I don't know much about kpop World i opted for easy to converse threads. But when I read I don't have the right to have an opinion, when my taste in kpop is formed according to YouTube's recommendations, I made me chuckle a bit, YouTube recommended is not something one should underestimate, atleast I don't.
