Making fun of the biggest band and strongest fanbase in the world was not funny. Calling BTS "unusual guests" at the UN General Assembly was misguiding because they are ambassadors of the UN and earned the UNs special presidential envoys for future generations and Culture for the Republic of Korea. They are not "unusual guests", they belong there, and the general meeting would not have been complete without them.
Moreover calling the BTS ARMY "15 year old girls", is an inaccurate perception because most of us are 18+. And who said that we are all girls?
