Oh! It makes more sense to me now.
Vincent, you asked: "Is there a difference between free marxist and anarcho-communist?" I don't know, but I thought of morphing "free market" as is used by conservative demagogues into "free marxist" to suggest that socialists believe in freedom, too. What the U.S. Republicans haven't figured out yet is that they are under oppression. They live under the heavy rock pile of elitist capitalist subjugators. And they don't even realize it.
Air pollution? Sounds interesting... Is there a difference between free marxist and anarcho-communist?
