Your falling in the trap of assuming that Scotland has "one attitude fits all" whereas there tends to different attitudes in different areas, if you take Glasgow as an example, many many people there feel more Irish than Scots, a lot of this is to do with football and "other factors" that I am tring to avoid mentioning, a lot of this is due to the mass Irish migration to Glasgow to work in the shipyards, Billy Connollys ancestors were Irish, I think his grandfather was called Kinnealey and anglicised as Connelly. indeed along the west coast there is considerable "Irish" connections, as there is in Liverpool and Birmingham. along the east coast there is much less of this and you will see football rivalry is still present but much less "intense" as I say the issues between Celtic and Rangers is a factor in the Irish links. as Celtic FC was founded by an Irish priest in 1888 for Irish immigrants, it attracts people who identify with Ireland/ Irish culture.

as you head north, attitudes change somewhat there is less identification with Irish culture and more with traditional Scots culture.

As far as the relationship with England goes, nearly everyone i know has connections with England, either through a relitive that lives/ or was born there or through professional connections, there is a perception abroad that the English hate the Scots and VV however its not really the case, there is in matters of sport a lot of rivalry, however Scots like Andy Murray, David Couthard, the late Colin McRae, have massive support south of the Border, and many English premiership teams are popular in Scotland. indeed a large percentage of people in England and Scotland are unaware of specifics in terms of the union, independance issues, etc.
