Analysing 'Hairspray' through a lens provided by Macdonald

Phenomenon: 

Most of the general public welcomed the integration of both races together, as seen from their reaction when Inez won the title of Miss Teenage Hairspray.

Lensing question: 

Macdonald argues that Mass Culture is undesirable because it produces a homogenized culture, resulting in the destruction of values because of its eagerness to demolish social distinctions and also democratic nature that rejects discrimination. 

How does his argument change the way we understand and perceive the desirability of the abovementioned phenomenon?

Grounds for comparison: 

The process of homogenization can be seen as being embodied by the integration of the black and white races as seen from the phenomenon in Hairspray.

This is because the triumph of Inez can be understood, in Macdonald's point of view, as an example of "breaking down the old barriers of class, tradition, taste and dissolving all cultural distinctions", since voters had to be non-discriminatory in their judgement of Inez's talent, before they could bring themselves to support her. 

Main claim: 

In my opinion, Macdonald's argument of the undesirability of Mass Culture applied to the issue of racial discrimination in the case of Hairspray is invalid.
