Very common? Utter rubbish. I’ve never come across any anti-English sentiment in many years travelling around Ireland
Maybe you just don’t see, then. I suppose that you’ll also disagree that the country is still deeply feudal in terms of county loyalties?
Now, I’m not talking about pitched battles on the streets or signs in shops banning Brits, but I think one has to be fairly blinkered to be oblivious to the presence, not too far below the surface, of prejudice. It’s going to be less on the West side and in Dublin, but the further away one gets the more likely one will hear evidence. It’s all done, typically, in a tongue-in-cheek, Edinburgh-Defence sort of way, but catch people in the right mood and it’s extremely easy to coax local, national or, less commonly, religious prejudice out of people. Compared to England, where I’ve spent most of my life, general attitude is notably more prejudicial. Only rural Sweden eclipses it, in my experience. The USA is probably too large to generalise, although it’s not exactly renowned for its outward-looking attitudes.
For clarity, I’d like to note that I disagree that “hatred of the English is part of the Irish psyche.”. I’m talking about the existence of prejudice. As I said at the beginning: what you don’t see is because of your sight.
