It's a very common misconception that French Guiana is a territory or even an independent country.
No matter what the standpoint is, having different answers to the same quiz is the exact opposite of being consistent. So I dont see how you can say this.
In this specific case, and your comment being a direct reply to sumguy. Because I know usually you do stick with the same standpoint.
So you can explain your standpoint, but that doesnt change the fact the other quiz excludes the UK.. so is not consistent with this one
