IF you subscribe to the definition that a continent is an entirely isolated principal land mass disconnected from all others and surrounded by water, that is true.

but i have news for you, most people do not use that definition. most geographers don't.

that is why most people "get it" when a person refers to africa, and particularly "black dominated africa" and no do not come back with the same ol bullshit questions about what is "africa", what "country" in africa for the sake bogging down and sidetracking discussion where the people involved understand what africa is, who africans are, etc.

this is all that needs to be understood.
