I don't know about hate but I don't have much respect for her as an artist. Her whole shtick is date guy, lose guy, write song about how it was all guys fault because Taylor is a flawless human being. Rinse and repeat. It's kind of been done to death.
Gimmie a break. She is an excellent writer. That is why she is a better artist compared to most in any genere. Maybe you don't get her lyrics, or like her writing, but you're not a young girl in her early 20's so I wouldn't necessarily expect you to. Her lyrics relate very directly with her target audience. And anyone that actually knows her songs knows that not every song is about losing the guy. Often times they stay together (Love Story, Tim McGraw, Mine, Our Song, Ours, Sparks Fly). Sometimes the song is about her wanting the guy back after they split up (Back To December). Sometimes it's about a new relationship starting (Begin Again). The idea that ALL her songs are about 'The Breakup' is basically what people that know very little about her like to say... which goes back to the OP's point. Why?
