With the greatest of respect, a response of "illustrate your points of complaint [about us] with examples" is kind of case in point. You phrased it very politely and I promise I'm assuming good intent, but it is kind of funny. I don't think anyone needs convincing that there's plenty of egotism and single-mindedness here.
Personally I would point to, very broadly, any discussion at all on finance or multilateralism.
The top comments on HN tend to have a very poor understanding of what the EU even is, how it works, what value it provides, and what it can and (especially) can't or shouldn't do.
Similarly, there isn't a huge amount of sophisticated discussion around banking and finance. I actually detect a hint of sulking some of the time, that there's this other difficult and well-paid field that the average HN commenter just does not understand. This was a bit more obvious a few years ago when Quantitative Easing and Bitcoin were in the news more often, but it still occasionally bubbles up under Matt Levine articles too.
