Lev Davidovich Bronshtein to be exact. "Trotsky" obviously changed his name to sound less Jewish. Leo Trotsky (aka Bronshtein) was an Ashkenazi Jew. Lenin was also an Ashkenazi Jew (mixed with a Tatar, and Slavic folklore equates Tatars with Jews anyways probably because the Ashkenazis and Tatars were both Khazars).
Karl Marx was also an Ashkenazi Jew with a Jewy-sounding real name I forget at the moment. His father and grandfather were popular rabbis and Marx himself has Rabbinical training of some sort IIRC. He was no doubt trained in the "art" of Jewish rhetorical trickery known as pilpul.
Most communist "revolutionaries" and practically all of the Bolsheviks were Jewish. It's no secret. It's never been proven that Stalin was Jewish though but it has long been speculated. He has Khazar facial features.
Other bloodthirsty "revolutionaries" such as the "Young Turks" were proven crytpo-Jews (Donneh)
On the "flip side" of communism you have so-called Randism. Ayn Rand was an Ashkenazi Jewess and sociopath. Some of the libertarian types around here advocate her for some reason, probably cause of Ron Paul. But a Jew is a Jew and none of these Jewish socio-economic and political "philosophers" should be advocates by real humans. Instead we should be advocating our own. Going from one Jewish idea to the next doesn't solve the root cause of the problem in the first place and that problem is Jewish through and through.
