Not sure who you are addressing in your post Notanan or why it matters to you quite so much but for many, an Irish passport offers the benefits of being able to go and live elsewhere and this especially applies to the young. In addition, I do notice that the 'living in France' group I belong to on Facebook appears besieged by British people intending to go and live in France!
The number of people who might need the Irish consulate is tiny though of course, one never knows. I have never felt English so I'd be happy to request and I still have family in Ireland.
The other issue is the cost of a British passport, why would I bother when I have an Irish one. And also, I love the friendly smiles you get from passport control personnel when they see your Irish passport, you definitely do not get the same reaction when they see a British one, especially now!
