Gibraltarians are not primarily of British descent, they are descended from people all over the Mediterranean.
Oddly enough, none of the people you mention want to be absorbed by their mickey mouse neighbours. Maybe if they weren’t so mickey mouse eh?
Also, in the case of Northern Ireland, which was largely settled by Scots in the 16th-17th century, you are on tricky grounds there even by your own standards. As Scotland was invaded and occupied by the Ulster ‘Scotti’ tribe (hence the name) from about the 5th century onwards, in which case the settlers were merely ‘returning home’ if you like. Even if that wasn’t the case, it is laughable for an American to be dishing out this argument unless he’s a native american.
As for Falklands, there were no people living there prior to British colonisation, so to all intents and purposes, the British people who live there are the aboriginal population. Putting them under the jurisdiction of another country against their will would be an act of imperialism that regardless of any wrongs that Britain might have done in the past, does not justify a 21st century wrong against British citizens living in the only land they have ever known.
“Oddly enough, none of the people you mention want to be absorbed by their mickey mouse neighbours.”
That was the idea of planting colonists there to begin with, eh?
The northern Ireland example is absurd; much of western Europe was Celtic, and as they were pushed westwards they were left with corners of France and Spain and the islands of Britain and Ireland. The Saxon invasion, followed by Vikings and Normans, added to the mix, but the Scottish Celts remain distinctly different from those of Ireland and Wales (who differ from each other as well). Scottish Protestants were planted there to remove Catholic Irish from the land (and replace them with livestock); the Scottish were in no way “returning home”. Nice to see them today asking for the independence they helped the English deny the Irish centuries ago.
If Britain planted a flag on some uninhabited island along the Florida coast we’d have something to say about it; we conveniently ignore the Monroe Doctrine when it benefits white English speakers to do so.
