The problem with Canadian identity is that we constantly get bombarded with American media. When i was a little kid, around 6 years old or so,i actually thought that i lived in the States with all the comercials saying stuff like 'we have locations all over the country" with an accompanying map of the US. American culture is so overwhelming that it is unavaoidible, no matter where you go. In Canada, we do not have a fundamentally different culture than the US. So we need to define the rather subtle differences between us. In order to do that, we need to say "We are not _____, instead we are ____".
As far as the subject of american ignorance goes, there are ignorant people all over the world, and it would be ignorant(

) to think that this does not the case in the US. However, i believe that the question is of how many ignorant Americans there are. I don't think that most Americans fully realize their status, influance, and impact on the world. Undoubtably, some Americans are aware, but most are, in the purest sense of the word, ignorant of it.
