The Sound of Music is racist.

I knew I was right to dislike it.

To be more serious I would argue that the subtext of agrarian fascism winning out is not the specific focus of this film but rather a fundamental flaw with Western conceptions of purity and nobility (in the sense of a noble spirit, not the elite class). We know that nearly all the time urban areas are more progressive and more tolerant than the countryside and yet we consistently have the myth foisted upon us that the countryside is where true decency resides. Whether this is due to the simple misunderstanding that because rural locations are prettier and pleasanter to reside in the inhabitants will follow suit or it is a more deliberately fostered myth by right wing elites wanting to justify their base and rural right wingers mythologising themselves. Regardless Americans will be most familiar with this concept in the contemporary praising of "small town values" by the GOP.

To go further into the link between idealised rurality and fascism I recommend Jonathan Meades' documentary about Nazi architecture:
