LIES! EVIL LIES! HOW DARE YOU BESMIRCH MY PROUD IRISH HERITAGE WITH YOUR BRITISH IMPERIALISM!? A THOUSAND YEARS OF SLAVERY OVERTHROWN IN A GLORIOUS REVOLUTION AND SUFFERABLE CIVIL WAR FOR THIS?
(My tribute to Eric, who finally left)
Actually, the Britons were one group of Celts. Celts existed all over the British Isles, France, parts of Spain and Germany, and even Northern Italy. The Franks (pre-Gothic), Scots, Picts, Angles, Welsh, Irish, and Britons are all Celts. But not all Celts are Britons. This is like saying all Greeks are Attic, when in fact, not every Greek is born in Athens.
