The single White feather as a symbol of cowardice comes from cockfighting and the belief that a cockerel sporting a white feather in its tail is likely to be a poor fighter. Pure-breed gamecocks don't show white feathers, so its presence indicates that the cockerel is an inferior cross-breed.
This is an idea that I like. A lot.
Gordon Brown has cowardly shied away from fighting public elections, from seeking any popular mandate for his rule—he bottled out of a general election, denied us our promised referendum on the EU Constitution and has now refused to stand a candidate in support of his consistent assaults on our Ancient Rights and Liberties. Since he has denied us a voice at the ballot box why not show our Prime Minister what you think of him? Send him a single white feather in the post.
This is a most amusing idea, I think. Simply find a white feather, pop it into an envelope and post it to: The Prime Minister, 10 Downing Street, London SW1 2AA.
And feel free to display this image on your blog: let's spread the word. Only 21.6% of the country voted for NuLabour at the last general election, and no member of the public has ever voted for Gordon Brown as Prime Minister; we could get a lot of feathers delivered. Let's make this bigger than the Ban Darling campaign!
I like to imagine Gordon, in the coming weeks, opening hundreds of envelopes over his breakfast—each one containing nothing but a single white feather.
Slowly the madness mounts as he frantically tears at the next envelope and the next and the next—though he knows what each one will contain, he cannot stop himself. His eyes become wilder, the tick in his jaw works harder and slowly he becomes surrounded by thousands—millions—of white feathers.
Brown's increasingly frenzied twitching as he opens the envelopes sends the feathers whirling into the air, landing where they will—in salty porridge, cups of tea; nestling in hair and lodged in pockets; covering the carpet and twirling in the sun streaming through the windows...
And finally, the police officers outside 10 Downing Street look at each other in shock and then spring into action as they hear a final anguished scream...
UPDATE: Raedwald points out that it may not be that easy to get hold of a white feather, so many thanks to the commenter who pointed out that you can buy some magnificent ones here. Why not buy a pack and distribute them to your friends...?
