If religious teaching is really so dangerous, why do so few people of any age profess any religion?
I went to predominantly catholic schools. Almost without exception these contained quite a number of children who were not catholic and a number who were not Christian. We had separate RE lessons,
I cannot remember on any occasion being taught to hate or be suspicious of people professing other faiths. Like most children in the schools I attended we did not live in catholic communities. Neighbours, friends, workmates and family belonged to every faith and none. Living in a pluralistic community means children mix with all denominations all the time and have friends and family among them. This is not conducive to prejudice or indoctrinisation.
The real danger is in living in faith based communities, whether these are in Northern Ireland or some cities and towns in Britain. In an area where 90% plus of the children in a school are of the same faith, the local school, whether faith based or not, will be a faith based school. Communities where children never meet people of another faith, never work with them or have friends among them are where prejudice and fear live. Not in religious schools.
But of course admitting the problem is communities not schools is so very political incorrect. Much easier, Don Quixote -like to make a big deal about jousting with windmills. than try and find ways of dealing with the real problem.
