I dunno, there's a good moral argument for giving a fairly mild ration of shit to somebody who insists on using a little experience to draw sweeping conclusions. It happens so commonly and so persistently that I do think a little bit of applied loss of face might be helpful. Hot stoves and all that.
I understand the sentiment but isn't the web confrontational enough already? I always think of the people on the sidelines who might be lurkers, interested in engaging the community, contributing, whatever and who read those kinds of comments, thinking: "There's no room for error, those people are really aggressive". It's just computers, nothing life-threatening so I like it when we keep it as civil as possible.
That being said, I second the content, Europe is way too heterogeneous an entity to draw any continent-wide cultural conclusion.
We mix Southern Spaniards, Sicilians, Ukrainians and Bulgarians with people from the Faroe Islands, Austrians and Scots, this is a wide gamut bunch.
