Mr.Adams you understand the Quebec motives very well.
Personally I do not see a few hundred people wearing those headscarfs.
I see here a continually tested secular culture. Quebec wants to be secular and you said the reasons very well.
BUT for the very first time immigrants are testing the charter of rights to gain concessions on diverse subjects. 
For the first time a group of immigrants simply does not want to fit in but wants to impose his will on the people who let them in.
We are in the first inning of a long , well organized and well financed crusade. This community does NOT accept our values and our secularism.
Quebec is especially vulnerable because of its french language, also spoken by muslims from Morocco, Algiers and Tunesia.
In the long term we will have 3 solitutes. The French, the Anglophones and the Muslims.
NEVER before has an immigrant minority done such a rejection of the people who took them in. WE are infideles and they could not car less about our secularity.
