I find it everywhere I go, people like to dump on the yanks, love to see them lose at anything. I reckon they are all just jealous.
I am not living in USA or Canada but I can tell you, I have met some rude, obnoxious, arrogant, cocky, whatever canadian travelers, as well as yanks, brits, germans, etc. There are ignoranuses of every race, creed, color, gender, nationality and whatever other classification you can think of.
Does canada have any strong contenders in any sport except hockey?? But then again who won the Stanley cup this year, was it Boston? And were there riots anywhere afterward???
