Wish Me Away: Chely Wright's documentary about coming out and country

I've yet to see Chely Wright's documentary, Wish Me Away, that chronicles her coming out and being one the first openly gay mainstream country performers, but Sam Adam's review  for the AV Club encapsulates the problem with country music as an institution, and the stereotypes that go with it:

Country music is one of the greatest casualties of the culture wars. The vibrant form that once had room for drunken layabout Hank Williams and pot-smoking longhair Willie Nelson has been codified as the soundtrack for red-state America. While its musical boundaries continue to expand, encompassing Shania Twain’s Bollywood dabblings and Toby Keith’s horn-section swing, its subject matter is constrained to an immutable series of tropes: God, the flag, cheap beer, pickup trucks, the troops, and not much else.

No other genre of popular music is so intrinsically tied to that America. Even when the stereotypes don't ring true -- a lot of country artists are, in fact, liberal -- country is permanently tethered to religion (the christian kind), family, and conservative "values." I read Wright's book last year, and some of it was achingly sad. I half wanted her to abandon her country roots, shave her head and a make a loud, aggro punk record and know that she could leave that world and all the grief it's caused her. But doing that doesn't change the bigotry within conservative, mainstream country and adds to the illusion that homophobia is nonexistent in every other genre of popular music.
