The article referred to in Mr Tait's letter is to be found here and this is what parents thought:
The research, by Vauxhall Motors, found 30 per cent of Scottish parents would teach their child at home, with 60 per cent saying they did not trust the education system.This is fantastically good news. Scotland is often portrayed as a profoundly socialist country although the four-party system here makes it look as though Labour support is much larger than the numbers who actually vote that way. But, even so: "60 per cent do not trust the education system." The people know that socialism doesn't work, even in education. It's up to libertarians to hammer on about the alternative.
