Ah there’s no real animosity these days. There are a lot of “stupid Irishman” jokes the English like to tell but that’s based on waves of Irish emigrants to England in past generations who would’ve been quite poorly educated. The jokes continue but they don’t bother us anymore cos we regard ourselves as better educated than them (always like to point to this to illustrate why niggers get offended if you call them niggers - think are only insulting if you know they’re true). Most of the other stuff is just the banter we have to have on these isles to make things liveable - the English laugh at the Irish and Scots as drunks, the Irish and Scots laugh at the English as lightweights etc. It’s not to be taken too seriously really.
