That is not what the article claims. It claims that racists use that as ploy to hide their racism, not that the claim is necessarily racist.
The author does not allow for non-racist criticisms of culture and religion:
Jenny Noyes said:Hating and fearing other people because of their culture or religion and claiming that is different to racism shows a totally elementary and outdated notion of what race means.
It seems that the only element of cultural difference Australians can agree to tolerate is food (as long as it's not Halal) - all else must be erased and replaced with white, Christian Aussie values and practices. Well sorry, but that's just racist.
No one in that article made that claim. From what I can tell, the critics said it was insensitive or wrong, not racist.
Then Hamad ought not have her headline be "When 'Timeless' Fantasies Turn Out To Be Incredibly Racist'. If the fantasy (the video) isn't racist, what does that headline mean?
And if the standard defence is that Hamad doesn't write her own clickbaity headline, she ought to clarify that in the article.
Again, this is not what the article claimed (although it is the closest summary in this OP). I believe the argument that author makes is that ethnic food served out of context is a form of cultural appropriation.
There's no such thing as "ethnic" food, or rather, if there is, every food has an ethnicity, just like everyone has an accent.
I wonder if the author thinks that Chinese people eating KFC is cultural appropriation, or if she herself meditates on the history of the hamburger or hot dog before she takes a bite.
