You make the common mistake of confusing English (English is an ethnic identity)with being Being British.
A bit like confusing being Zionist with being Jewish.
When i have i ever Pretended to be English and why would i want to be English, although i have some English ancestry from the West Midlands apparently and a bit of Irish, still over 3/4 Scottish, Galloway and the Scotland /England borders.
My passport says British on it and not English, because by ethnicity I am British , definitely not English or Irish.
You need to educate yourself about your own country.
North British and proud.
"North Briton" in the context of Ulster refers to the 17th-century influx of Scottish settlers (often termed "North Britons" or Scots-Irish) during the
Plantation of Ulster, establishing a Protestant, Scots-speaking community. These settlers, predominantly from Lowland Scotland and Northern England, were encouraged by the British crown, fundamentally altering the demographic and cultural landscape of the northern Irish province.
