Thought: like Communism, Socialism, Modern Art, etc., simply bring up the topic of Marx results in visceral responses for and against and usually garantees that your audience isn't going to take you seriously.  Unfortunate.  Result is that those who want to avoid the whole debate and maintain the status quo just dismiss these ideas by dismissing Marx.  And those who use Marx to argue these ideas too often aren't willing to acknowledge the reality on the gound.  For whatever reason, bringing up Marx invites simplistic ideas.

Maybe we ought to try making our points without mentioning the man.  Even if he was right about a lot of things.  (BTW, People who say he's outdated PISS ME OFF. How many millions of people are still living according to the teachings of the Bible? Ack!)

Those who can make you believe absurdities can make you commit atrocities. -Voltaire
