Marcus, the president of the neighborhood improvement group, tried to decide if asking the local community dispute resolution center to help resolve the parking$/$playground conflict would help or hurt the situation. Michelle, the case worker at the center, told him, $"$In most cases, mediation can help disputing parties find a solution that satisfies everyone. But even when that is not possible, the process can reduce tensions and encourage better communication. Sometimes with better communication, parties can find a way to meet each other halfway if they cannot reach a mediated agreement."

Marcus said, $$Well$,$ it sounds like we could benefit from mediation then! When the idea of a parking structure first came up$,$ Diana and other neighbors ignored the suggestions made by Tony. Once people started listening to Tony, it became a fight for one or the other, and I know neither side is going to give in$."$

Based on the information from this conversation, which conflict style does Marcus think Tony and Diana are currently using?
