You should get your PTSA and the school board involved in this problem. Remember that you, the student, are not the customer; your parents are. Your Principal is not senior management; the school board is. Those stakeholders, along with a local mentor representing the community, need to become engaged in addressing the issue. Get a meeting scheduled and go in prepared and with an open mind. Think of positive things to say, and have constructive ideas on how to resolve issues.

If you have other teams in your school district, ask their coach to also attend to provide information about their program.

Also make sure you address the issues as they relate to academics and your college prospects. If you walk in talking about your "club", you will be at a big disadvantage. That's not the school's mission. You should mention any financial support you get from non-school sources. Your activities are not a drain on the school system, but rather a positive extension.

In the off season you can prepare alternative plans to form a community team. You can even offer that to the school and see if they actually prefer it. I can predict that they will not. Don't present it as an ultimatum, just as a possible solution. But don't kid yourself, converting to a community team is hard and not without a fresh set of problems. Even the worst school environment has certain advantages.

And know that you are not alone with this problem.

PS If you are in the DC Capital Region, I'm happy to help face-to-face.

PPS Also check to see if you have a school or school district ombudsman, someone with the actual role of bringing two parties to the table to resolve conflict.
