For me the main issue is that if your talking about idols being disrespectful at a certain event that gives fans a list of potential groups it could be and thus attacks start on those groups who attended who probably didn’t do anything. In the case of ive they seem to be an easy target to hate with Kpop fans and them being at this event gives another excuse to hate on them
It’s better to either name the groups or at least be more vague and not specify what event your talking about so that way it could be anyone and not a narrowed down list
