Find me any definition that is or is not Europe. If you can draw a line between the Mediterranean, Baltic and Atlantic, sure. Britain, Ireland and associated islands? Iceland? Greenland? Scandinavia? What about to the East over land? Is Russia European? How much of it?

The definition of “Europe” is useless because the definition of “continent” is useless. Australia: does the continent of Australia include Tasmania and/or New Zealand? Some folks claim both Americas are one continent because they were connected at the Isthmus until we sawed Panama in half. If we classify them separately, where does North America end and South America begin? My middle school taught that North America only had three nations on it, Canada, USA and Mexico. Mexico is on North America but Belize isn’t? What about Greenland? Africa: Madagascar? The Arabian peninsula? Asia: Japan? What about India? Is the “subcontinent” part of Asia?

Europe is the least convincing of them all. Pretty much nowhere else do you have to start mentioning “culture” when drawing a border between continents.
