The key is finding the axis along which your interests align, and finding an individual enemy whose motivations are enough to trust. If you find for instance a halal butcher who the corporate player is trying to crush, you might find yourself someone with means and motivation to help you improve the world somewhat before your division reasserts itself. It isn’t so much ‘let’s compromise’ as it is ‘we might never get along, but destroying the meat corporation is a matter of survival for both of us’
