what the issue with british and irish people ?

is no issue now days with them but way back British never liked Irish  one time  as they took their jobs off them ..suppose some Irish have not forgiven the nasty way they were treated 

There are Somali, Afghan, Roma gypsies , Nigerians everywhere in Ireland and England now that the world does not know about

British Irish None

British Unemployed IRA since 1922 was the Only Problem Northern Ireland decided to remain British the IRA said we will murder your babies if you do

the IRA murdered babies for nothing

Me I would have Filled up the Prison Ships with IRA and sailed it out to the Middle of the Atlantic and sunk it Problem solved

all the Problems after 1922 were caused By Terrorists mainly the IRA

What do you mean? I live in Britain, there are a lot issues. But, you need to specific.

None the Only Trouble was with the Unemployed IRA after 1922when they were Made Redundant

they wanted a United Ireland and Millions did Not so they Used to use American Money to Murder Babies

That goes back hundreds of years. Starting with Henry VIII, British monarchs gave away huge parcels of land to loyal artistocricy in Ireland (and the Americas), including land that had been farm by Irish people for centuries. Then in the 1850s potato famine, the English refused to offer any aid to Ireland. And the Irish were not given equal representation in the British parliament. Oppress a people long enough and they're likely to cause problems. 

Today None i went to Cork in 2017 had a great time and I flew the Union Flag and Immigration never asked any questions Just Viewed My passport and said welcome to Ireland

Historically, the British thing to do, was sail up to a piece of land we hadn't visited yet and explain to any natives the joys of ownership, and how that applied to them.

Many objected and we then pointed out the joys of guns.

This went on for some time.

Eventually we were persuaded to give most of it back, but some bits didn't want to be given back and demanded to remain. This was a bit embarrassing and one of them is called the Irish issue.
