In this site there's a trend to treat Europe as a monolithic entity and pretend it's awesome. Any criticism gets taken as "Americuns" being ignorant and europe is awesome.
In reality, I see a lot of unwillingness to accept the political reality and pretend "we are better than USA" via political apathy and coping.
People react negatively when you point out polítical facts they don't want to see. It's easier to look at USA with an air of superiority. This also happens the other way around, of course, but HN demographics make one more typical.
