You're so funny! Talking about pointing out the 'flaws.' Honey, there's nothing that can be done about that. This forum is an open discussion for anyone to say whatever they want about K-pop and then move on, again, not about the so-called 'flaws' you speak of.
Plus, I used to know such person you're defending, they sure do cause quite a stir. I've seen them constantly attack others for their viewpoints in a very dismissive, nasty, and brash manner when someone just wanted to express their opinions on the K-pop industry. Yet again, this forum invites every discussion related to K-pop, and nobody should be torn down for it.
