WTF is a "only speaking British nation"?<quoted text> The only speaking British nation is England others are not. Until you understand that, more of your garbage.
Are there other British nations that do not speak?
Or should it be the "only British speaking nation"?
In the last case, you are - again - wrong.
The word "British" refers to the Celtic inheritance of Britain.
The "British" languages are Celtic languages. These include Welsh, Cornish (extinct) and Breton. Breton is spoken in Brittany, France. It is spoken by former immigrants from England, who escaped the Anglo-Saxon conquest.
Hence, England is not the only nation where "British" languages are spoken.
