I mean, I'm sure the average Britisher in the 1950's was spouting off like the Publican, just in a 1950s way. I doubt there was some golden age where all Britishes spoke perfect Queen's English and wore tweed jackets and smoked pipes and studied Horace.
Kind of like if I were to say there was never a golden age where every American studied Locke and had the constitution memorized and worked every day honestly with his hands on his own land in order to support his wife and children, who were proud to contribute to their sustenance, able to be educated in simple 1-room schoolhouses and make pies to leave out on the sill. Homespun cloth and protestant work ethic and tri-cornered hats and love for the union. citizen soldiers, pious to God and the ideals of Democracy and Freedom.
Except, of course, America actually was like that, I'm pretty sure. Whereas, you know, England is just a country made up of people who have changed over time and been influenced by the times they lived in and stuff. History.
I don't really know what I'm trying to say, here. Maybe I want to see a British comic take on America. Due to having read a Stephen Ambrose book about D-Day at an impressionable age, the first thing that comes to mind is his description of British troops standing on one of the beaches and shaking their heads at the sheer volume of crap the American soldiers had carried all the way across the ocean, only to dump it on the beach when they realized how heavy it all was. Piles and piles of all the stuff the British were on short supply of. Basically everything I love and hate about the US is summed up there, and in general in that book/WWII as I understand it. I think it was Asherdan who said you can't have one side of that coin without the other, and I am inclined to agree the more I think about it.
