People do love their tribal hierarchies to give them a sense of identity and belonging.
i.e.
Country: Great Britain
Nation: England, Wales, Scotland Ireland (and, some would maintain, Yorkshire)
Region: Yorkshire (where it should be), Scouse, Geordie, Londoner, Caulkheads (look it up), Brummie, Cockney etc.
Football Club (often at the opposite end of the country to where the 'supporter' lives.)
Class: Working, Middle, Upper, Twits
Jobs: Bankers...., no we won't go there I think.
Pastimes: MODEL BOATERS, pistonheads, yotties gardeners and just about anything you can think of.
Pastime Niches: Scale, Fast Electrics, Model Yachting, damn great things with IC engines stuffed in them etc.
All these define our identity and who we are. (You will see I have omitted Politics & Religion in accordance with Forum rules)
