Is it OK for Katy Perry, Selena Gomez, and Julianne Hough to Use Other Cultures as Inspiration? [POLL]

It seems Katy Perry is getting both good and bad feedback for her 2013 AMAs performance, which makes me think back to when Selena Gomez had a Hindu-inspired performance on the Billboard Awards and received only good feedback, but when Julianne Hough dressed up as a character from 'Orange Is The New Black' and dressed in black face, she received only bad feedback. So, what is or isn't acceptable in the pop culture? Where should the line be drawn? And does the feedback on a celebrity come based on the way they have built their public figure to be?

Critics against Katy Perry's AMAs performance seem to have mixed feelings. Some say the performance was "racist" because Katy and a few of her back up dancers were not Japanese, but others have come to Katy's defense saying the creative thought behind the "Unconditionally" performance was a result of her prior trip to Japan where she spent time with a few geisha women and was so inspired to translate the beauty she experienced in her AMA performance.

Which brings me to my next thought: why is Katy Perry's performance being considered as "racist" but yet the Hindu-inspired performance by Selena Gomez for the Billboard Awards was completely acceptable? Also we can compare Katy Perry's "yellow face" inspired AMA's performance to Julianne Hough's "black face" inspired Halloween costume, which offended so many. Julianne had no choice but to make a public apology.

I believe all three of these acts were a result of an impulsive thought of creativity, but do you think Selena Gomez received less slack than the other two because she has built herself as the all time American girl image? Or was Selena's Hindu-inspired Billboard performance less offensive than Katy Perry's geisha inspired AMA performance and Julianne Hough's Black Face costume for this past Halloween?
