Yeah completely agree with that. I was born & raised in North Wales Welsh mother Irish father. I've never verbally called myself British. Any form (with the option) I select Welsh or other & put in Welsh. I went 39yrs never once sang god save Queen, and I'll die having never sung god save king. I don't class myself as British,I don't want to be British. Yet on official records, obviously I would be seen as British.
Thats just life.
