If you believe that I am a Marxist, this proves that you don't know anything about Marxism.

 I reject Marx, because I have studied it in depth -- I have read Capital among other Marxist works -- and realized both what Marx got right and what he got wrong. Marx explained extremely well the history and problems of 19th century capitalism, but completely failed when it came to "so what do we do now?" (I thank my religious history professor, Dr Bense, for getting me to understand this.)
