"Excuse me, do you have any T-shirts with Stalin on them? I see you sell this shirt with Che Guevara on it, but he only killed, what, a couple hundred? But Stalin! He's killed tens of millions!"
"No, sorry, we do not stock Stalin T-shirts."
"Oh, OK then. ...What about Hitler?"
Che Guevara is not just a fashion icon. He was a totalitarian, communist revolutionist who killed those who got in the way. He did not respect life and revered martyrdom. He was an enemy of freedom.
