I haven't, altho i understand ur stance on big bang.
Altho individual members like Taeyang, do u follow him? Seems like a chill dude .
My groups that i stanned has done questionable things too. Ofc i wont follow someone with a criminal record or someone who judges others based on race, sexuality, ethnicity etc.
But i try to give a second chance to ppl that made stupid comments , cause i know i was young and did and said stupid shit cause i didnt know that would hurt someone. The difference is my mistake isnt blasted on social media for everyone to see, but celebrities' are. If they are sorry, apologize and try actively to change i of course follow them still.
