Ruth Dudley Edwards (Comment, September 11) writes of Sinn Fein as "a malignant growth on the island of Ireland" that, in the course of its progress, has brought to a close the lives of many.
But she could have added that it's a malignancy that has now taken a further turn: instead of espousing a separatist, socialist republic for Ireland (and bombing and killing for that separatism), Sinn Fein is now espousing an Ireland fully integrated with the European Union.
How this turn to integration with the EU came about - on which there has been no public debate - within Sinn Fein is worthy of investigation.
Yet, such an investigation could only unveil how the integrationist stance was argued through, if it was argued at all. It would not deal with the malignant growth itself.
The roots of the malignancy are in a Christian world, of which the conflicts within Islam today are reminiscent. That is what we need to get into the classroom.
That world, even to more recent times, saw in the tolerance of error, heresy. Not true tolerance, but indifference, as Archbishop Sheehan's Apologetics - once used as a textbook in Roman Catholic schools in Ireland - taught until the Second Vatican Council necessitated its withdrawal until revised.
Nevertheless the traces of old mindsets remain (Malachi O'Doherty, Comment, September 11), only the other side is seen as discriminating.
Although Sinn Fein is indifferent to religious issues, they feed Sinn Fein's malignant growth.
