"One type defines "Russian" very broadly to include all of the peoples and religious groups that have traditionally lived in the territory of the former USSR or before that, the Russian Empire. The key call of these nationalists is to reintegrate the territory of the former Soviet states.
A second type of nationalism is a much more exclusive and even racist ethnic Russian nationalism, one committed to a pure Russia free of "polluting" peoples of other ethnicities, or at least those who are not Slavic. The key call of these nationalists is to prevent immigration of unwanted groups and, for some, to bring Russians or Slavs "stranded" abroad back into the Russian state's domain."
