The word "gay" derives from happy but most fags seem to be pretty depressed.The word "nation" stems from "natal" (birth). A nation IS a people and only people of that nation should have any birthright to citizenship.
Nations are about the people but what that people is is largely created over time.
The "Dixie" of the southern USA have their own culture but they only acted to form their own nation due to particular political circumstances and that identity has since eroded greatly.
France literally banned non-Parisian dialects of French and has worked insanely hard for centuries to create an identity based around the Republic and Citizen.
Austria was ecstatic to join Germany and has since changed their mind... golly.
Muslim Tatars, Buddhist Mongols, Atheistic Slavs and Paganistic Siberians will proudly call themselves Russian.
