Rebel with a Cause

I was working on a crossword puzzle recently and one of the clues was "Rebel with a cause".

The answer was "Che", referring to Ernesto 'Che' Guevara, the Argentine, Marxist, mass-murdering revolutionary.

So, I'm guessing that the puzzle's author (Matt Ginsberg) is one of those people who have not a clue about Che's "cause".

Well, read this and get a clue:

 "Murdered By Che"
     "During his vicious campaigns to impose communism on countries throughout Latin America, Che Guevara trained and motivated the Castro regime's firing squads that executed thousands of men, women and children."
