Separatist movements actively thrive on divisions and bitterness between people, not the most honourable style of politics, it has to be said.
Nationalism will always cultivate a sense of superiority, and whether it's the PQ or the SNP in Scotland or any manner of other nationalist/separatist parties, there will always be times when one has to question whether such parties have crossed the 'racist' line.
The same could be said about their opponent, often. There is many anti-French people in English Canada.
That's true. It's nevertheless no justification for nationalism on either side.
