I'm Irish, lived in England for many years, and we're pretty annoyed. I would say there's nuance though, including about which regions voted what way - I think there's more understanding of why the vote happened, but great frustration at realising that Westminster does not give a shit about Northern Ireland, and that we are going to be horrifically affected economically for something we had no say in. Huge economic impact, food shortages, expensive price increases and the potential of a return to violence up the motorway. It irks me people on here almost willing no deal so no voters will get what they deserved - it will screw a lot of us as much as you, and many more than the average well-off no voter.
Some of us are also quietly concerned about the likelihood of a united Ireland coming about not through things genuinely moving in that way via consensus but through the rest of the UK showing such disregard for NI that a bare majority thinks they might as well throw their lot in with us, and the impact that will have.
I was at a dinner in Brussels a year or so ago with people from across Europe, many of whom lived in Brussels some who didn't, and found myself defending the Brexit vote a bit to my surprise. Everyone there thought it was outrageous, and a sign of British arrogance, and varied from bemused to incensed by it. My experience of living in England was utter shock at how little people knew of Europe's role. In Ireland, we would often know who Irish Commissioners were, MEPs are serious elections: These are positions and jobs held by career politicians who are featured on the news and known by name. Living in the UK I was shocked by how little any news coverage dealt with anything from Europe except the comedy stuff - straight bananas etc .
The organisation I worked with had a 'how the EU works' lunchtime talk - it was relevant work wise - and I could not believe how a room full of mostly college educated, London-based, politically engaged people did not know basic facts that most Irish students would have learnt in primary school. To that end, I think internationally the vote was misinterpreted, and it seems almost inevitable to me. But despite what the press says - and despite being in a position where we'll be most effected by no deal - I still think most people don't want the UK to have preferential treatment on principle. There is a feeling of, you've made your bed, you've taken up a lot of our time, you either need to compromise or deal with the outcome.
