"Good old Britannia" - aka two thousand years of stuffy, conceited, unimaginative, inbred, upper-class idiots lording it over anyone with the audacity to be poor or not born to a noble family, perpetrating any number of disasters and defeats by ignoring good advice from people without sufficient arbitrary social rank to be paid any attention, and generally opposing any progress or innovation on the principle that any change from the status quo could only represent a potential depletion of their absolute, undeserved and unearned power and authority.
Traditionalism, inflexibility and arrogance, as practiced by the former British Empire and now finding popularity in the United States' general attitude to the world at large, have more to answer for in the way of colossal disasters than just about any other social force.
"Britannia?" Great British Tradition? I'm British, and I say you can fucking keep it. What the world needs is intelligent, decent people working out the best way to do things right fucking now, not a bunch of automatons deferring their decisions to people who have been dead for centuries and whose policies were tailored for their world as it was then, not ours as it is today.
