The EU as described here -
https://europa.eu/european-union/about-eu/eu-in-brief_en is something I fully supported and wanted to remain a member of. I now need to go to the trouble of getting my Irish passport to retain those benefits.
For all its flaws - and there are many, as there are in any complex organisation- it is, in my view, "a good thing" and the UK will be a poorer, meaner, smaller place for having left - yes, economically, but just as importantly for me, socially and culturally.
Am I "patriotic" about it? No. But then I'm not patriotic about Britain either - to be aggressively and defensively proud (and most patriotism seems to manifest itself this way) of where you happened to end up on a little bit of rock floating through infinite space seems a bit odd to me, but I realise I'm probably unusual in feeling that way.
