Do you not understand the difference between a colourless role and a cast-specific role. Its understandable in hollywood to have roles written with a specific racial background in mind - I.E. Dreamgirls specifically cast black female leads as it was a direct parallel of the Supremes who were all of African American backgrounds. Dreamgirls explores underlying issues of racial struggle and classism in the entertainment industry, again another reason why they need to cast it very specifically.

Again your comment holds no weight on this article since the writer didn't write the lead of Chicago to be a particular colour and plenty of ethnic people have assumed the lead role (including Michelle Williams) on broadway.
Around 40% of the USA is ethnic, so 4 in 10 main characters should be ethnic to reflect this.
