How can you get your friends to accept you for who you are?

I am someone who is a scene kid and I am always getting pushed around saying that I'm a poser. Well I'm NOT! Just because I like what they like such as, (Paramore, Breathe Carolina, Dot Dot Curve, Asking Alexandria, ect. Really anything Screamo) And I am in 6th grade and I were eyeliner to school. They think it's stupid and "poser-ish". Please can someone help me!!!!!!!!
