I will aslo Point out that People living in Northern Ireland are entitled to both British and Irish Citizenship or whichever one you are preferential to.

The Unionists see themselves as British (Even though they live on the Island of Ireland and are technically Irish but that is swept under the carpet ) as in a member of the UK. Nationalists see themselves as Irish Citizens and members of the Republic of Ireland.

The whole issue of British and British Isles is confusing, but generally Great Britain is seen as the main Island comprising England, Wales and Scotland.

It may not have been an invasion but it was certainly a hostile takeover. This is what I was always taught.
It was a hostile takeover, but so was everything else throughout time. This occured not long after The Thirteen Colonies got planted and kicked out the Indians.
Life was different then, a main rule is never to apply today's morals to eras past.

The decendants have as much right to Live in Northern Ireland as the decendants of the Indiginous Irish.
