I am not trying to be insulting, I am just pointing out why many people don't think of England as a "country" in modern times. I think the examples I provided are actually quite relevant. Between us, the one who is actually throwing insults would be you.
In any case, other international organizational examples that do not recognize England, Wales, or Scotland as "countries" include Interpol, the World Bank Group, CERN, the Commonwealth of Nations, and the World Trade Organization... the list actually goes on and on...
The United Nations and the vast majority of the world define "countries" as sovereign states. England, Wales, and Scotland (and Northern Ireland) are not sovereign, but the UK is. England and Scotland WERE countries up until the Act of Union 1707 when England merged with Scotland to create "The Kingdom of Great Britain" and THAT country grew with the addition of Wales (and later Northern Ireland). As I explained before, the member entities in the UK are are more like states in the USA or provinces in Canada.
You may dismiss this information as "rubbish" but that doesn't make it untrue or invalid. And I assure you, I am not uneducated.
