@Rep.. The people who use the slogan "Pure Laine" were the duly elected Government of Quebec at the time.
The pro French movement The FLQ (Front de Liberation Du Quebec) , A convicted terrorist organization who kidnapped and murdered a politician, used the term and gave it it's modern popularity.
It means, Pure Wool. You can make your own assumption as to what that entails.
In order for a Duly elected Government to get into power with a slogan such as "Pure Wool" regularly tossed a round in it's rhetoric, the electorate must have some racist and xenophobic tendencies.
In the last referendum on Quebec sovereignty. The Separatists lost narrow decision.
The leader of the Separatists, who was also the premier of Quebec stated publicly is his defeat speech.
"The reason we lost my friends , is because of money and the ethnic vote, democracy has not been served"
Political analysts all agree what he meant was Money= The English and the Ethnic = Immigrants.
It was also determined that what he meant by democracy not being served is that if the vote was held amongst the "Pure Laine" only.
He would have achieved victory. He in essence called non French people false citizens of their land and suggested that, the next time there is a referendum, they should not be included in the vote .
The irony is The French or Pure Laine population comprises of well over 70% of the whole population, whilst over 80% of it's citizens speak fluent French.
Even a Vote Held amongst those of only Pure Laine Descent might not have yielded the victory.
There were also a disproportionate amount of votes declared "spoiled and invalid" in predominantly English speaking areas.
Almost all of them were clearly votes against separation. In some areas the "spoiled" votes were as high as 11% compared 1.7% in other elections .
