Math genius Grigory Perelman is Jew born in Russia.
When something bad, always mentioning that he's a Jew.
But when something great people DENIES deliberately person's Jewish ancestry , then he called ''Russian',
if Perelman is 'Russian' than we can call Russian even Lenin, Trotsky, Kaganovitz,Yagoda etc.
Btw, the Jewish Mafia is a RUSSIAN Mafia, not Jewish
in Russia under soviet regime and even at those days Jews were second sort citizens who were discriminated in every possible way.
But every time a JEWISH GENIUS makes headlines world wide ppl scream and say that he is Russian!
And I scream NO he is not Russian he is a JEW.
