The family was allowed to re-board and continue their trip. The Steward who had a problem with them was kicked off the plane.

A friend that is a pilot From Spirit just updated me on this situation. It was a CRO no a FA that tried to remove the family from the Plane. The CRO was remove from the plane, the Family remained on the Flight and made it to the destination.
I heard that when the family was kicked off, in solidarity with them the other passengers all got off, too. This forced the airline to let everyone back on, while the steward was kicked off. This is what need to be done more often. We need to stop submissively accepting whatever our ‘betters’ decide to do.
