Oh dear - what a tangle.
I do not think that the wearing of a white poppy has no value; but simply that the current world situation is so overwhelmingly dreadful that it feels such a small thing.
But I also agree that awful behaviour is part of the human condition - when I look back and think about the news that has flashed past my eyes during my lifetime, Biafra, the IRA, the Bade-Meinhoff gang and so much more, it seems that terrorism and war have always (and likely always will be) with us.
I wish that wearing a white poppy would change that in some way. Let us hope that the Peace Pledge Union can do some good work - I wish them well, but in my heart I think they are no match for the vested business interests that fuel the arms trade with the collusion of the politicians.
