From the GAME OF THRONES: When Jon Snow was getting cohorts out of jail to go north to hunt the walking dead, there was dissension as to why they should work together. Jon answered because they were all breathing. So Jon united them with what they had in common.
Compare that to the human population that has diversion and hostilities between groups with different aspirations / ideologies. Well, what common ground could be called upon to unite all for the survival / welfare of all. I’d say LOVE. Let love guide our thoughts, actions and interactions. Let us not be played to fight among ourselves. If we must fight, lets unite against the UN-loving (those who instigate us to distract us from seeing their unloving agendas, or for their monetary gain at our expense).
Lets lead our actions with our hearts. Unite against the ‘walking dead’ or those ‘walking without love.’
