I wish this didn't ring so true. It is so prevalent that for those who were raised locally and who went through said university schooling it is still painfully easy to distinguish from which student union in which city these guys originate based on how they treat each other, even when they graduated decades ago. Which ironically means that they are guilty of the kind of primitive tribalistic nonsense that they project onto other cultures.

... actually, now that I wrote that out, I guess that could partially explain a few things as well.

(and I'm well aware that this is not a problem unique to the Netherlands, but it still sucks)
