You were saying that it is a double-edged sword. So one edge is positive and the other may potentially be negative. What is the other edge you are talking about? What are we afraid of? Personally, if I asked people a simple question about whether they would like to send their children to a French minority school, and 250,000 people said that they would like that and it would be really good, I would try to provide them with those services.
Are we afraid that we might get answers that are going to force governments to provide services to people who otherwise would not be asking for them?
