Well, the next step is simple. The girls all stop all payment of their dues immediately. They look for a house or two and rent it together and move out. Then, sue the sorority for breaching the contract/agreement to get all of their past dues back. If they are the majority then there will be no girls left in the sorority and the chapter will have to shut down unless the tranny future molester fuck-head can pay to keep the whole house open on his own.
