If you tell me that Wikipedia is not a legitimate source for the above information, shall I point you to 10 other sources that will corroborate the above??
You must have been born on another planet.
1.One is the Marxism is derived from the Hegelian German tradition of a dialectical view of social change.
2.Marxism argues that socialism is a possible, but not necessary step between capitalism and marxism. The more revolutionary the more likely this step should be avoided.
3. Read: http://en.wikipedia.org/wiki/Marxism and notice how they use socialism and in what context. They use it in opposition of Marxism and Communism.
