People who live in England with full British citizenship and people who originate from English families for as long back as they can trace, for generations and now live elswhere. Those who honour English culture and the laws. Those who embrace the government system and who respect The King and Christianity. ( while also respecting the right to practice other religions).
Personally I identify as Irish 60%/English 40%. Though I am a fifth generation Australian citizen every drop of my blood comes from the British Isles for at least 800 years.
I used to feel Australian but I am not indigenous so I am regularly welcomed to my own country (my land of birth where my ancestors shaped the govermment, the agriculture, the laws, education, language, wealth, architecture etc.) in ceremonies acknowledging the indigenous history only.
So I rationalise that I must be indigenous to Ireland and England. That is where my DNA, culture, my advancements, education and roots stem from. It is fair that I can claim British identity and hopefully recognition in the form of reciprocal rights, passports etc.one day if Australia becomes hostile to me.
Most English of all are the non human aspects. The English plants, birds, insects and native creatures and habitats.
The flora and fauna of all countries deserve to be protected. Human movement by guests and citizens alike, should always sustain the environmental identity of the place and the health of the waterways.
