No, the Founders weren’t cranks. They had a political program, principles, and support.
The Bundys have none of these things and are cranks, trying to provoke a response. Even the people they were supposedly “supporting” didn’t want them to do this.
The “Founders” were considered “cranks’ by most of the population. Not only the dyed in the wool Royalists were against them, but so were the chicken liver cowards who hid until the fighting was over. The Royalists mostly left for England in the next ships or went to Canada. The rest of the “uninvolved” profited by the actions of the heroes.
