This is such a typically 'Canadian' view of things.  And arguably reflects just how naive and ridiculously immature we are as a nation.  Either to ourselves, or on the international stage.
On the question asked, standing up for 'values'?  How would those same individuals respond if given a 15-minute overview on some fundamental economic realities?  Such as:  who are our major trading partners, and with what percentage of trade; how trade represents what percentage of our national economy; and how trade represents what percentage of our national employment.  Then re-ask the question:  would you support Canadian 'values' being rudely imposed on some other nation, if it led to you personally losing your employment? or your taxes going up in the absence or lessening of trade with that country?
On the second question being asked:  come on, really, do we think 'Canada' has such an overbearing presence that we are 'owed' the first visit of a US president?  Come on!  Grow up a little.
