People who hate people just because their two races/nations once had a dispute. Its fucking stupid (the notable exception being the French...cheese-eating surrender-monkeys).
Coming from a guy whos profile says he's british that statement is a bit rich. Considering England was normally the conquering country so you might feel differently but for the country who suffers the most or who didn't instigate the fight it may not seem so stupid. I'll ask you one question that could explain some Irish peoples hatred of England.
Would so many atrocities occurred in Ireland had England never invaded?
Think of the history of the two nations and see that by working together the two islands could have both benefited.
Try telling a Polish person that hating Germany is stupid or any nation who has suffered at the hands of another. I think you'll find yourself alone in finding it stupid.
Thats not to say that I don't agree with countries that have a history working together. People have to move on and work towards a better future so cooperation is needed and I think the relationship between Ireland and England is the best it's ever been except for continuing problems up north.
