No Greg, the point is how harmful the religious beliefs are. We recognise and permit a reasonable range. Nutters are nutters, whatever God or the voice of a dead dog tells them.

Opus Dei believe in the mortification of the flesh. This will out in their entire attitude to discipline. As Moo parallels above.

We prosecute (and rightly so) those who torture children for example by putting chillis in their eyes to punish them for being witches, or mutilate women in the name of religion.

Why put the same mentality in charge of an entire education system (even temporarily). We bar (or might be about to expel) Abu Hamza, why not Ruth Kelly?
