Agreed although interpretation is key and the human race has proved incapable of getting on since before region existed.
That’s a lazy myth. Some factions have historically not got on but history shows us time and time again that all races prosper when the fighting stops and negotiation, trade and peacemaking prevail.
The Vikings proved it.
The EU proved it.
The abolishment of slavery proved it.
Gay rights proved it.
Women’s enfranchisement proved it.
History is full of examples of peace, unification and tolerance prevailing countless times.
