I may be wrong (I usually am) but I tought that the white poppy was to remember the innocent (non military) casualties of war and that the red poppy was a fundraiser for the Earl Haig fund to help ex servicemen and women. If some fluffy peacemonger has hijacked the white poppy as a symbol of anti warism, then he has it wrong.
I have even heard that there are purple poppies out this year to raise funds fr animals killedin conflict!
