but Mamamoo 

When kpop idols mess up and stan twitter have to bring Mamamoo into the mess for no reason at all ignoring the fact that they apologized four separate times.

When stan twitter are pressed about Mamamoo's success and feels the need to spread lies and defamation for retweets and likes

Starry Night is a good song but Mamamoo are racist bitches that did blackface 14 times!
That idol messed up but Mamamoo are colorist, racist, and are completely homophobic..

But Mamamoo 

A new version of " But Namjoon ". It's a phrase stan twitter uses when their faves do something problematic. (Strangely, this phrase is mostly used by Armies, who has been through the same thing) They use it when they want to redirect the hate to Mamamoo even though they apologized (2 letters + apologized in front of the fans next day) 4 hours after being called out. Mamamoo are one of the few idols who owned up to their mistakes but to this day, stan twitter still keeps spreading lies (etc: "They did it 484884 times even after their apology" or "I've heard they did xxx too.") about them and constantly harassing their fans for stanning Mamamoo

A: We should stop hating on idols who apologized sincerely.
Also A when their faves does something problematic: xxx did this but Mamamoo... Yall forgot about them easily...

Or

A: Kpop is problematic
B: You have no say in this you stan Mamamoo (Also stans another problematic idol)
