A friend pointed me to an interesting and very well-written article published in Slate last year (September 24, 2004) by Paul Berman titled, "The Cult of Che: Don't applaud The Motorcycle Diaries." I don't know how I missed it, since I check in with Slate and Salon every day, but the kernel of it is this:
"Che was an enemy of freedom, and yet he has been erected into a symbol of freedom. He helped establish an unjust social system in Cuba and has been erected into a symbol of social justice. He stood for the ancient rigidities of Latin-American thought, in a Marxist-Leninist version, and he has been celebrated as a free-thinker and a rebel. And thus it is in Salles' Motorcycle Diaries."
