The only solution to situations like these is for people to talk to each other. I've been involved in running sports clubs for years and we have had plenty infighting in the past. Everybody has their own point of view as to how things should run. It has split the place in two and the only way to get back together was to talk and actually listen to the other points of view.
Nobody is ever 100% right or 100% wrong. It usually lies in the middle somewhere.
