I have never heard of anyone call themself a "Westministerian",or mention the "City of Westminister",I doubt if anyone cares about it The City of London is not the same thing as London the city. I have no idea where this bollocks about Germans has come from The City of London is the old,tiny part,first populated many years ago and is a city in its own right,it is only just over a square mile in size. It still has the Banks and prestige it has always had As London grew Westminster was established "next door"to try and draw away influence from the City of London,it is not in the same league,or has the same respect and "power".
Most of us just recognise London as a whole ,unless we work in the "city" or belong to a Guild.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
