Why do people dislike Miley Cyrus?

Is it because she has grown up? honestly, I myself have grown up with miley and bunch of other girls my age. Personally, I love her. Her show was what kept my smiling when i would get into fights with friends or I had problems going on in the house. Her song "the climb" is what legit kept me alive through high school and listening to it now gives me chills because i use to hear it when i was a baby sophmore the lyrics have touched me so much. so why would people hate her? sorry if the paragraph has lots of grammatical mistakes, I'm in a hurry!
