My parents are threatening to send me away if I don't play basketball for a team I hate

I'm applying to private high schools. I'm playing basketball on my school team currently, and I love it. I also play on a team that I've hated since the beginning, and I finally want to quit before the season gets started. However, my parents say I can play on either both teams or neither. I think it's unfair because it's up to me if I want to play for a certain team. I was planning on playing basketball for the high school I get into, but if that means continuing to play for the team I hate, then I wouldn't want to play in high school. Now I don't know what to do! My parents are threatening to send me off to a different home if I don't play. I just want to run away.
