I agree, Ernie, that is what Remembrance Sunday should be about. It is what it is about for any right minded individual. It isn't a celebration of war, it isn't about the political reasons behind a war, it's about "a sombre reminders of the horrors of war".
From what I have heard so far, it certainly wasn't an organised protest from any anti-war organisations. From previous experience, however, there have been a tiny number of extreme loonies on the anti-war side of things who have chosen to use Remembrance Sunday for this cause. They do not represent the overwhelming majority of people who are in the anti-war movement. .
