Problem with parents and going to church?

ok im 15 years old and unlike some people who don't want to go to church i do believe that there is a god and in christianity. heres my problem: my parents make me and my slightly older brother go to church wih them, and the church is full of alot of whites and its basically for old people, and there is no youth group. my parents just don't understand that we don't want to go to that church and it won't help our personnal relationships with god. what do i do?
