Apologies, I got side-tracked with the house renovations and forgot to check back here!
@queenofaries I think when foreigners think of quintessentially English , they think of The English countryside. Quaint little villages.traditional pubs.
Yes, that's exactly what my mother thought, and what she missed whilst not in England! 
@PigeonofDoom (love that name btw
) I agree, when I lived in London in the 80s, it was a diverse place. Diversity to me means a wide range of race, culture, beliefs, customs. I suspect London was always so, history's not my strong suit but given the amount of invasions this land has seen and trade with other nations...
@floraloctopus Somebody who was born in England is English. As the nationality on our passports is British and people who become citizens are British then it's possible to legally become British but not English (or Scottish, Welsh, Northern Irish).
I'm born in London therefore that would make me English, but I do not identify with that because I was taken back to Australia at a few months old and raised there, until my early 20s when I returned. I was very much an Aussie when I arrived. 
BUT (and this is where I find things confusing) you say people who become citizens become British but not English (or Scottish, etc). In any other country this would not be true? So why here? Is it because we are the United Kingdom (4 nations contained under one roof)? If we were not, and England was a standalone country then gaining citizenship would make one English, surely?
