> Canadians have a blind spot about praising ourselves for how tolerant and inviting we are.
That's true. For big cities the situation is better but not nearly as good as it could be. Technically Canada is 'colour blind', but in reality it definitely isn't, which is a pity.
I'm not even sure if it is better than all of the US, both countries have enough variation that some areas are ahead of others in both countries.
As for it being inflammatory, I think it's perfectly ok to outline the shortcomings of a country as long as its done in a realistic way without an agenda.
My own (current) country, the Netherlands has gone from being fairly tolerant to being outright hostile to foreigners, especially those of Maroccan, Turkish, Romanian and Polish descent (for a variety of reasons). In the last elections the ultra-right scored the biggest gain of all parties, a full 15% of the electorate now backs them. A very scary development.
