I am also a Quebecer, and experienced the stringent RC upbringing. I was lucky because I was what they used to call "un maudis anglais" (English Quebecer). In our schools and homes religion was not so overwhelming.
Between 1916 and 1925 women got the right to vote, except Quebec. Here the church ran the government and were not favorable to women voting, however they finally got it 20 yrs later.
Women we commanded by the church to be barefoot and pregnant, once a year the priests would visit the homes and if the woman was not pregnant she had to do pennants. My mother-in-law had her first child at 16, in all she had 18 with two miscarriages. These are just 2 examples of what went on in Quebec there are many many more.
Having participated in several forum discussions on this subject I am of the impression that those who lived outside of Quebec did not live under the thumb of the RC church like we did. My Mother's generation and mine have fought to free us from the shackles of the RC religion.
I believe in separation of state and religion, that also includes school and religion. Many other religion have Sunday School and why not! This way parents can choose to send their children of not.
I do believe children need some kind of religion and moral instruction but not in daycare or schools were today there are people of many beliefs together. However that includes no religious dress nor symbols (kirpan etc) and no special conditions granted for beliefs.
