"I think you underestimate people Jim"
As someone of Irish extraction who lived in London throughout 'The Troubles' - I think I do not, but there again, that is my personal experience, yours may be different - be happy to consider it if you put it up.
On several occasions I experienced the prejudice towards the Irish - the 'T'ick Paddy' image being among the most common.
It was beautifully summed up for me by a customer when she told me, "we have Irish neighbors so we always have to check under our car before we turn the engine on".
There's a wonderful book - may still be available, entitled, 'The Same Old Story', a history of prejudice towards the Irish - quite horrifying
