Like Mr. Corbeil, I have a great deal of difficulty contemplating this, but for different reasons. As I said, many rights-holders are very misinformed about the impact of attending a French-language school. In one province, up to 64% of parents believed that, if their children attended secondary school in French, they would lose their knowledge of English and they would not be able to attend university. This is false, but it's what parents believe.
If you ask parents whether they want their children to attend a francophone school, they may say they would rather their children attend an anglophone school to make sure they can study at university in English. All sorts of false beliefs can be propagated in matters of interest.
