1) Is it correct to use "ALL" with a State or Continent?
For instance, ALL AMERICA, ALL ENGLAND, ALL AFRICA, etc,
2) If it's correct, can the expression also be used with the meaning of "all the people" of that State or Continent?
For instance: "All Sweden oppose(s) racism" (all the people in Sweden oppose racism).
3) What about "oppose" in number 2)? Plural or singular?
