How to get my parents to accept the real me?

my family is very traditional and find my ways to be unorthodox. My family watches football, goes to church, listens to classic rock and country music, very conservative. I on the other hand listen to hardcore death metal (screamo), i dye my hair and wear it longer, i wear skinny jeans and band shirts and v necks, i am an atheist, i enjoy non conformity, i would like to get piercings but they probably wouldn't let me, etc. I would just be able to enjoy being myself without my family calling me gay and goth, and just accept me for who i am
