I take the opposite view OG.
As far as i aom concerned, I am British / English by an accident of birth, and nothing more.
This does not confer on me some god-given right to adopt either a superior attitude to other nations who were born elsewhere by a similar quirk of fate, and it absolutely does not confer on me any propriatorial rights about the piece of the planet I occupy, as though it is 'mine' by birthright.
Therefore, I feel no sense of 'patriotism' what ever. I have done nothing whatsoever to become 'British', and apart from being a law-abiding tax-payer, i cannot claim that my contribution to the culture or well-being of this section of the planet entitles me to get chippy about other individuals who may choose to occupy it with me.
I do, however feel a profound sense of relief that i am born in to an rea with freedoms and support systems that remain the envy of the world, but again, that is my luck and good fortune, to be appreciated.
That is not the same as picking fights, moral, religious, or otherwise, with anyone who doesn;t happen to agree with my viewpoints and lifestyle.
I will not be flying flags, and certainly not be 'sticking my chest out' - I would feel faintly ridiculous doing so - World Cop or not.
