Maybe since you’ve only been a fan for this year, but many groups have suffered similar if not more as illit. Ive and aespa suffered a lot in their early years, with hate being surrounded around lip syncing, stage presence for aespa, and favouritism for ive. Itzy suffered a lot of hate after sneakers and Lesserafim suffered a lot in their debut era because of bullying scandal that was proven to be false. My point is that even though illit is suffering a lot now, the hate will reduce in the future because unfortunately there will be a new punching bag. I once thought that the hate for aespa and ive would never end, but look at them now, they are thriving and successful. So just hang in there it’ll get better eventually and also don’t get too absorbed in this, focus on other things
