I'm going to tell my drama team to shut the hell up
Why do you want to be mean to them?
I'm the team leader and I don't like to listen to them anymore.
That is not a good way to use your power. You should always listen to someone even if you disagree with them. You are setting an example and you should have a good attitude.
I'm going to tell them that I am going to be loud if I want to. I don't care if they follow me or not.
I don't see a bright future of your drama team. If you have this attitude, people are going leave it soon. If you want  to continue working keep your ego aside and try to work as a good leader.
