Oh for heaven's sake.
The newest hot button issue being debated around tables of the socially- conscious is Bill 44, a bill to include into Alberta's human rights law the right to exempt their children from classes teaching concpets the parents disagree with (for example evolution, religon, sex and it's orientations). Many liberals are declaring this would "[strike] another blow against critical thinking in schools and extend one of the bleaker elements of its history".
I do not have children. I'm not sure I will ever have children. But I know, between my parents and the revolving door of "grab-bag" teachers (some of whom were excellent, others...less so) who I would trust with my upbringing. I may not believe in what you say, but i will defend, to the death, your right to teach it to your children. This is being touted as a way to eliminate discrimination that many parent pass on to their offspring, but this is not the vehicle to do it in. To do so, we need to eliminate discrimination in the adults, not estrange children from their parents. Society today has enough things ripping the family apart, we do not need another one causing children to question the first authority they will ever know.
Furthermore, teachers are not all the overarching bearers of unbiased information that we would love them to be. Some have feelings. Some are politically motivated. What can be done to combat the uncomfortable suggestion that a teacher may have access to hundreds of fresh minds? At least parents only have access to their own child. A bigoted parent will do less damage than a bigoted teacher.
The common objection, here, is that knowledge is better than ignorance and that children should be aloowed access to all schools of thought to encourage tolerance. This is true, and I agree, but this is not the place to do it. If a tree is rotten on the inside, do we cut off the leaves, grafting them onto an already burdened tree? The proper step would be to nourish the base of the tree and watch the branches heal. Children are in difficult enough situations. Lets not make them worse.
