UPDATE: I contacted the creator of the NewsMutiny article, who sent me the following message regarding the quote:

“I didn’t invent it. I got one of those emails myself, but I also know it has been published and attributed to Marx by a number of newspapers around the world over the past few months, so if its not Marx, the greater blame belongs on their shoulders, them being actual news sources vs. my homegrown satire site.”

I absolutely agree that we should not require or expect a satirical news site to verify the accuracy of quotations. I do, however, place blame on ordinary newspapers that spread misinformation due to a lack of careful fact checking.
