Dressing children up as Disney's Moana this Halloween is racist, according to one parenting activist.
Parents should also think twice about letting their brood dress up as Elsa from Frozen because her character promotes "white beauty".
Writing in her popular blog Raising Race Conscious Children, parent blogger activist Sachi Feris urged parents not to dress their children up as characters from backgrounds different to their own as it "makes fun of someone else's culture".
Although many would see the strong-minded Moana as a perfect role model for their child, Feris said it's racially insensitive and risks parodying Polynesian culture, the MailOnline reported.
Describing her own discussions with her five-year-old daughter, Feris said: "Moana is based on real history and a real group of people.
"If we are going to dress up a real person, we have to make sure we are doing it in a way that is respectful. Otherwise, it is like we are making fun of someone else's culture."
The parent, from Brooklyn, New York, revealed that after her discussion about "cultural appropriation" with her daughter, the young girl decided to go as Mickey Mouse instead.
The blog has attracted almost 100,000 shares on social media and attracted a string responses from other bloggers since being published.
Moana, a 3D animation, was one of Disney's biggest hits of 2016, raking in $640 million at the box office globally, while also winning praise for having a non-white female character, based on mythology from indigenous Polynesian people.
However, Feris warned parents about allowing their children to go as the South Pacific princess unless they come from the same background.
The blogger also took aim at Disney's Frozen character Elsa, another of her daughter's Halloween picks, adding: "I feel like because Elsa is a White princess, and we see so many White princesses, her character sends the message that you have to be a certain way to be 'beautiful'".
The concept of "cultural appropriation" has sparked widespread discussion in recent years with white westerners being urged to be wary of borrowing from other societies.
Wearing sombreros, growing dreadlock-style hair, wearing Bindis and Native American outfits are among the trends white westerners have been told to avoid.
The growing movement has caused a backlash, with many calling the trend humourless and a method of censorship.
One writer for the National Review hit out at the absurdity of applying cultural appropriation to Halloween, writing: "Do you have to be Transylvanian to dress up as Dracula? Do you have to be Egyptian to be The Mummy? Do you have to be dead to be a ghost?"
While a parent commenting on the blog wrote: "Kids don't care about race. What do you think your kid is going to tell her friends? She can't be Moana because Moana is different race and culture?
"Then when one of her friends is dressed as Moana she's going to tell her it's offensive because she's not the same skin color.
"This is literally forcing your kid to be racist. I understand and admire the efforts to remain respectful but she's five."
