Was Stalin a Jew?

I have been asked the question was Stalin a Jew?  A quick search for an answer tells me that Jews want people to believe he was not a Jew.  Karl Marx was a Jew.  Joseph Stalin may not have been a Jew but he did not have to be a Jew to be a CORRUPT PROXY for the Jews.  Joseph Stalin was an evil dictator responsible for the deaths of tens of millions of non Jewish Russians after the Bolshevik Revolution.  The Jews raped Russia and murdered anyone in that country who could oppose their rule.  It would make sense to me for Stalin to be a Jew for that reason but he did not have to be Jewish to do that.  He could have been a non Jewish tyrant under their control.  Either way, Stalin served the Jews.  As an example of that, Stalin made anti Semitism in Russia punishable by death under his corrupt rule.
