You’ve deluded yourself. More party factionalism, putting party before principle, is the disease, not the cure.
Good stewardship of resources IS a good principle.
In any “just war” the most humane way to FIGHT that war is to fight for VICTORY as quickly as possible.
Factionalism will happen in ANY group of people. You have little understanding of human nature, psychology, group dynamics or politics if you think that you can keep ANY political party “pure”, even for a moment.
A Political Party whose members ALWAYS agree with YOU will ALWAYS be small enough to fit in the average Church basement.
