It is true that schools have a responsibility to help prevent the radicalisation of impressionable young people in their care (“Schools must play a key role in combating extremism, experts say”, 31 May). But, in addition to challenging their students’ misconceptions, teachers should be very careful not to peddle a leftist anti-Western agenda in which British and US involvement in Iraq and Afghanistan is used to “explain” terrorism. This fashionable but intellectually vacuous and irresponsible argument simply reinforces a vulnerable child’s sense of victimhood and further alienates them from society. It should be unequivocally emphasised that, in a democracy, an aggrieved minority does not have the right to aggressively undermine the parliamentary will of the majority. Disliking the foreign policy of a nation cannot possibly justify or explain murdering its citizens. The only civilised way to change society is by using the ballot box, not the bomb.
