What does Asian even mean? Is it an ethnic category? Racial? Linguistic? Cultural by values? Food? Religious? Cultural by art? Historical contact?
If we assume it has something to do with the sub landmass called Asia (magically not counting white Siberia or Georgia), then you are adopting white people’s lumping and othering of one of the largest and most diverse (by any of the above measures) subsets of humanity, subsets of which itself have much more in common with other “ethnic” categories.
It is idiotic, racist and colonial.
