People like that aren't really real fans tho, I wonder if any of those people even buy CDs ?_? When you make a real commitment to be a fan (lol I make it sound so official) you don't easily ditch your favourite because of drama, but hope they can overcome it and if they did something wrong (like drunk driving or posting a stupid tweet) you hope they learn from it and become wiser people... "Fans" who just like a song or two seem to be the ones throwing the biggest insults when someone they only kind of like does something wrong. Because they don't lose anything by letting them go. The people I saw dissing T-ara were people who liked Roly Poly and shit, but weren't actually fans, so it's not like they were truly abandoning them. How can you abandon something you never had?
The way I see it, when scandals happen these groups/artists lose a lot of CASUAL fans who don't necessarily even buy their music (of course some casuals do and that's a loss, but not all do), and they gain a lot of vocal anti-netizens... But seriously, after all the backlash T-ara got on the Internet, were they actually boo'd (by a CROWD, not like 2 people) or attacked or severely cast aside? Nope, nothing that serious happened; after some pre-recorded shows they returned to doing live stages. Antis just like to run their mouths.
Especially because any sensible person understands that IU didn't actually do anything wrong, I sure hope things will be OK for her sooner rather than later. I don't actually worry about IU's fans, but SuJu fans...
