Its pretty well written article with some very subtle hints of satire laced throughout. I believe she has a strong dislike of Texas, traditional values, and is ashamed of her family for being who they are. She yearned for freedom from the male dominated homestead, to lofty ivory towers, and Star bucks lattes of NYC. She sounds as if she was always an anti, but decided to hide her true feelings from her family until she moved out of Texas. She is obviously ridiculing her heritage, by the way she describes her family, hometown, Texas etc in the article. Basically she is writing to her liberal audience, and qualifying their views they share on the "rest" of America.
