Why is the border not then across Ireland. The EU happily shares borders with non EU countries with the customs at those borders. It could be that there has never been a fixed border and the Irish do not want to construct one. I can not understand why anyone thinks that allowing a foreign government to set rules and laws in part of your country is right, it would never happen in any other country in the world.
The people who live in Northern Ireland aren't ruled by a foreign government. The vast majority voted for the Good Friday Agreement (apart from the DUP) and to remain in the EU. The GFA was a compromise. Northern Ireland and the Republic of Ireland remained separate countries, but the EU allowed for a seamless border. Many people in NI already have dual citizenship and Irish citizens have the right to settle in the UK. Therefore, many people have freedom of movement, but the goods they want to trade wouldn't, if it weren't for the Protocol. Many people on the border rely on seamless trade. Many of them would also be happy to re-unite Ireland (apart from the DUP, of course). The NI/Irish border is not like any other border with the EU. There's history and feelings are strong. Being part of the EU allowed a compromise agreement (the Good Friday Agreement) to operate. Old tensions are re-surfacing.
