When the giant forest fire in Canada a year or so occurred, I don't recall hearing or reading of a single American expressing feelings of superiority over Canadians because they built the town with one road out and houses in the woods. 
These comments are a uniquely Canadian thing. 
The articles here and virtually every comment was supportive and somber. Then again, these are  the same people who rejected numerous offers of help from America and instead brought in a bunch of South Africans with specialized sticks for forest fire fighting in the particular terrain. 
While you get great joy out of people drowning in Houston most Americans think Canada is a friend. That's not due to mental impairment on the part of Americans. All of the credit goes to the insidious nature of the bigotry up there. Houston has a huge Spanish population. So technically it could be racism and not just plain bigotry.
