The Grand Orange Lodge of Ireland and the Apprentice Boys of Derry will soon take part in a march in Edinburgh to oppose Scottish independence. The march is organised by the Scottish Orange Order.
At face value it is what you would expect from a pro-British, pro-Union organisation. But in a significant way, this march contradicts the underlying political position of the Orange Order in Northern Ireland.
The Northern Ireland Unionist position is based on the principle that the island of Ireland is not automatically one political unit. They have argued, successfully, that it does not matter that they are a minority on the island.
What matters is that they are a majority in Northern Ireland, which is the part of the island of Ireland in which they live, and that gives them the right to be politically separate from the rest of the island of Ireland.
But that is the underlying principle of the Scottish independence campaign that the Orange Order is opposing.
The Scottish Independence campaign is based on the principle that the island of Britain is not automatically one political unit. They are arguing that it does not matter that the Scottish people are a minority on the island of Britain.
What matters is that they are a majority in Scotland, which is the part of the island of Britain in which they live, and that gives them the right to stay separate from the rest of the island of Britain.
And Scotland has been globally recognised as a political entity for centuries longer than Northern Ireland has.
So why is the Grand Orange Lodge of Ireland not supporting the right of the people of Scotland to determine their own political future, like the people of Northern Ireland, rather than being subsumed into the politics of the geography of an island?
