For them, forcing immigrants to adopt French would hopefully transform Africans, Asians, Caribbeans and South Americans into model Quebecers who mimic their hosts not only in language, but also in thought and demeanour.
It hasn't worked before and isn't likely to succeed in the future.
While many foreign communities have adopted Quebec as their new homeland, they largely have kept much of their traditions and culture, something that irks militants to no end.
Some communities have integrated on the English side of the language equation, some on the French side and some split, but whether on one side or the other, most of these communities have kept up their traditions, values and religious affiliation much to the chagrin of purists who demand that speaking French isn't enough and that adopting Quebec 'values' is necessary as well.
Years ago I watched with amusement the Bouchard-Taylor Commission on reasonable accommodations and as Premier Charest said a the time, it was the best entertainment on television featuring many crackpots and racists.
But perhaps the most poignant moment for me came when this statuesque Black Quebecer, an obvious immigrant from Africa complained in excellent French that 'they' (whoever that may be) are demanding that she eat poutine and maple syrup, an allegory that rightly explains language militants expectations.
A little later on in the hearing a North African complained comically that there wasn't enough foot(soccer) on television, again underlining the clash of cultures.
From a solidly white/Catholic Francophone society with a minority English community tucked away in western Montreal, Quebec is moving to a pluralistic melting pot, at least in the greater Montreal area, due to massive immigration and a precipitous fall in the birth rate.
Here language is irrelevant to those who see the 'barbarian' invasion as a threat to what Quebec used to be and blame the immigrants for staying true to their heritage, culture and religion, something bad when it comes to 'les autres,' but something good when applied to Quebecois de souche (old stock)
Generations later, these immigrant communities have stubbornly held onto their own set of values, infuriating language and culture purists who had assumed that these people would lose their religion, taste for ethnic food and cultural mores over time.
While Bill 101 forced these immigrants to adopt French, it cannot transform them into the image of their hosts, crashing the dream that Quebec could be multi-ethnic yet French and culturally homogeneous.
Language extremists are faulted for claiming that the sky is falling, but are largely correct. While Quebec is becoming more and more French, it is becoming less and less Quebecois in culture.
The stark reality is that the only way to stem the cultural derivation of Quebec society is to increase the anemic birthrate among Quebecois de souche, something that even the most strident language militants dare not suggest.
What language purists propose instead is unrealistic, placing the onus on immigrants to reinvent themselves.
Bill 101 was and continues to be popular among Francophones because it relieves them of the responsibility of safeguarding their own language and culture. It remains a convenient cop-out.
Support for safeguarding Quebec language and culture among francophones is strange in that the majority of Quebec francophones (57%) want to strengthen Bill 101, yet a majority (53%) want to be able to send their children to English schools. Over 63% of francophones want the right to an English CEGEP education. It's hard to make head or tails of those statistics.
And so the die is cast.
Unless Quebecois de souche increase their birthrate, Quebec will evolve where historical Quebecers and their society will have to share the province with those who speak French, but who are more religious and who hold different values, customs, food and traditions.
Bill 101 can't save Quebec from going down that culturally diverse road, only a dedicated effort to have more babies can, and that gentle reader, you and I both know it isn't going to happen.
