Some critics have maintained that (unlike modern nationalism, which is a creation of the 19th century nation state) authentic nationalism (as the Latin 'natio' would suggest) must be based in some form of genophilia and the sharing of ancestors in which sense The Vatican does not qualify as a nation-state since membership of Catholicism are scattered all over the world with no possible ties of ancestry pedigree.

There are certain ethnic groups who choose to form relatively exclusive communities based on their race. Most Australians are even OK with this. However, there are some who do not extend the freedom to express genophilia to white Australians.
