As a Canadian, you are being absolutely ridiculous. I assume you’re talking about the Fenian raids. But firstly, calling them a big antagonist is a major stretch. They really had a relatively small presence that wasn’t really related to Canada itself. Secondly, they were done by individual actors, so associating them with Ireland itself just seems silly. And finally, the idea that anyone in Canada is even slightly resentful over them is ridiculous. I can absolutely guarantee that if you asked everyone in Canada about the raids, at least 95% would have no idea what you were talking about. And of that 5%, 99.9% would consider it purely historically and not care about it in any modern context. If you explained the raids, then asked every Canadian if they were even slightly resentful toward Ireland as a result, you’d either be laughed out of the room, or they’d look at you like you were absolutely crazy. Most likely both. It is not a thing in Canada. And if you were resentful, it would be considered extremly weird and would make most people probably look negatively on you if you did so.

The majority of Canadians would not agree with you classification of Ireland, and consider it rude. They would also roll their eyes at you trying to utilize Canadian involvement WW2 to somehow support your comment. (And also at you disparaging Irish neutrality. Even during the war itself, very few were upset at Ireland for remaining neutral. The common thinking was “It’s perfectly understandable. Why would you go to war as a small nation when you don’t have to”. Nobody was anymore resentful towards Ireland than they were towards Switzerland or Sweden. If anything, they were thankful towards Ireland for bending on their neutrality and letting Allied shipping and airspace through)

As for your initial comment, nationhood and statehood are basically the definition of ambiguously defined concepts. Everyone agrees they are meaningful. And everyone agrees they should be different. But when to comes to specifics, everyone has their own exact definition. And very often, they overlap. Which means that despite the fact that people have been advocating for clarification for centuries now, they still remain vaguely defined and are often used interchangeably. But regardless, very few political analysts or historians would say it is the main the reason that Ireland was more conservative in the past. Either way, the majority of Canadians would not agree with your classification of Ireland towards present day, and consider your statments incorrect and way too abrasive.
