There's a reason companies take 80% of the profit. It's their job to take care of shit when shit happens, like with racial scandals and controversies. The idol's job is just to look pretty, perform and pretend they like their fans.
The most recent example concerns Giselle. Who is being burdened with all the responsibility but not SM, conveniently. This is why stans are just focusing on Giselle: because once SM is obliged to do their damn job they not only have to answer for Giselle's fuck up but FOR ALL OTHER SM IDOLS who underwent similar controversies. The last thing stans want is the public to be reminded or aware of the offensive things they have done in the past yet remained unaswered.
Unfortunately for Giselle, she is being put through the fire until it dies down. Ignoring the fact that Giselle can't say anything on her behalf because SM has full control of their idols' public expressions. And they are responsible for educating them on these matters.
