Re: British Isles? Wow, you managed to fail both Geography and History in two sentences!
“Last time I checked, the Republic of Ireland (Southern Ireland) was independent of Britain, and doesn't fall under the term "British Isles".
Where did you learn Geography? From some Victorian book saying the world was flat I bet”
As pointed out by many, many other people, the Republic of Ireland is part of the Geographic location known as the British Isles , Just like Canada and Mexico are in a place called North America.
As for the last point, the Victorians did not think the world was flat, after all, they had a world wide Empire, you would have thought they would have figured it out.
The Earth not being flat has been taken as fact for many hundreds of years, even Christopher Columbus, knew it was round, but he thought it was smaller than everyone else so if he went west he would get to India quicker than going east over land, as there was nothing but sea between Europe and India.
He was wrong.
And so are you.
