Wow. What a total misrepresentation of what happened. The mention of Article 16 made its way into a Commission document as part of after hours edits to a draft document. It was never actioned; it was never implemented.
And just to get another thing clear: the British erected that border in Ireland. It is the legacy of a 400 year old ethnic cleansing project still being resolutely implemented and supported by the British government.
Ethnic cleansing? I find it amusing that you play the voice of reason and come up with such dramatic lies! Are you, perchance, an Anglophobe? You forget, for one thing, that what we today would call "the British" have been in Ireland one way or another for hundreds and hundreds of years and vice versa. And it was the native Irish, called the Scotii (Scotia denoted Ireland), who populated what we know think of as Scotland. Should be ask the Irish to stop occupying northern Britain? The UK signed the Good Friday Agreement, which more or less handed the fate of Northern Ireland over to the island of Ireland, with a provision for a future referendum on Irish unity, effective pardons for Irish terrorists and no equivalence for British soldiers who fought during the Troubles. The UK, unlike most other former colonial powers, has handed over its dominions with relative grace. The idea of ethnic cleansing is so utterly abhorrent an accusation it could only come from the naive, foolish and spiteful (and very likely that common Internet troll: the Anglophobe).
