I personally think that when a fan of a particular fandom say that their group is “better” than another group or the “best” group out there, they are being very ignorant. Your bias group could be anything, SNSD, 2NE1, EXO, etc. but your group is not the best, nor is it “better” than another group. Individual preferences, and other factors will never allow anybody to say a group is better than another. People should learn that instead of being ignorant.
