I see no grounds for a lawsuit and I do believe you were rightfully terminated for insubordination.
As FrChuck said, unless you belong to a Union or have an employment contract it's employment at will. Many, many people are unemployed and I'm sure your employer replaced you with someone who was less difficult to deal with.
Sometimes you have to just keep quiet and comply if you want to remain employed.
