That explanation for what Marxism is, Janine, bears no resemblance to what Marx and Engels actually promoted in their books. What you call "Marxism" is true or false depending upon what definition you choose to utilize, as we live in an era where words tend to mean anything the person using them wants them to mean. Personally, I am using the classical meaning of the term. I'll allow others to define it as they choose, but it's not what Marx and Engels formulated.
