<S> Olds, buddy. Ya gotta accept a little responsibility for your actions. Maybe communicate with the TA instructors what your intentions are, when you are in there, that way if they think you might interfere they could offer you options to keep you out of trouble. The TA is not the only place you could have been practicing your Immelmans, you could have picked a field in the DA and not bothered anyone. So, you can learn from this and adjust what you are doing if you wish to positively interact with those you play with or continue as you were and bear the burden of being a contrarian.
Good luck to you sir <S>.
