Speaking as someone who is anti-war, without any affiliation to any organisation, the affair seems to show the British Legion in a light that marks them as not anti-war.
And after a brief search on the internet I find results which reinforce this with some of their previous historic decisions, for example refusing to change the wording cast into their poppy central sections to show a message requesting an end to war.
I applaud Eric Bogle for his composition and regret that this new rendition will not reflect his intended message.
