Well, there are many definitions. First could be those whose ethnic origin is from the British isles and who reside there. Second could be those who hold the legal and secular definition of having citizenship of Britain by virtue of birth or naturalisation but may not have ethnic roots to these isles.
Britania Romanus.
This side of Hardian's Wall all British Romanus, on the other barbarians. A 1000 years independence after that, mixed with rising sophistication of landed gentry... sailing out and believing to be the inheritor of Grecco-Roman Civilisation, those thousand plus old monasteries... input, genetic and otherwise, of Vikkings and Francs... from middle English to Baccon's
opus magnum... Britian of Rule Britania.... Noblesse Oblige... garnders and shopkeers...
Yes, Britain is and has been evolving. Difficult to pinpoint, yet so easy to say... British.
Monty Python? Mr. Beans? Roller or Bentley? Classes... lower and upper. Horses and Greyhounds..betting?
When we visit Britain of WW2 and in its aftermath... It is still the largest empire on paper... yet in 47' the biggest colony needs to handed over. In the 50's starts the journey towards Britain from the former colonies...
We need to place ourselves in the minds of local Britons... just less than a decade ago they were masters and now have to share workplaces.... oh, you... ****... oh, you indian... etc. etc. Echos can still be heard.. first and second generation knows only too well. Not gone away yet... EDL.
And yes, the people migrated there because they were needed... you know the rest.... 60's, 70's and 80's... from sexual revolution to Iron Lady era...and those famous strikes... as a byproduct Political correctness became vouge. British Pakistani, British indian, British Bangladeshi... classifications. What purpose did it serve?
From 90's onwards enormus effort has been exerted against racism and gender discrimination... many laws have become the norm... it advanced the Human Condition in Europe.
Yet, why... is there a need from the state to classify people because of their ethnicity? Not racist per se...but a distinct feeling of keeping the host state's cultural identity separate, perhaps?
So, what is British? How can a non White can become British then? Fish n Chips? Sheperd's Pie? Train Spotting?
Why do people feel the need to have separateness? Both the host society and migrants...
The indians have built there temples and do their festivals in the UK... they have kept their indianness alive.
The muslims have built their mosques and Pak traditional way is alive.
All communities have their distinct cuisines... thus creating more separateness. Same with TV channels and movies.
So, what is to be British then for migrants?
Jews remained jews all over Europe despite being there for what... 1000 years?
So, yes, I do agree that there shall remain this separateness.
Even a child from mixed marriage will always be seen first as the foreign race and then as British. When colour is involved... halflings, hybrids...mixed whatever you want to call it.
Is it only racial bias or something anthropolgical...say like humans are tribals at their core despite their education and whatnot.... it needs analysis.
I do believe that religion should not be carried on the sleeves... must remain a deeply personal affair between the maker and the made... a discourse of solitude.. Paradise Lost.
As we enter a great Unfolding Cycle.. I do percieve accentuation of 'otherness' will increase. Both good and bad thing really.
Apart from all the horrors and abuse of colonisation... one good thing that emerged from it is that world became noisy village and will keep going in that direction. Humanity will become a Hybrid down the road... never totally but significantly.
Now enough of this boring post, over to you!
