Che Guevara was a racist as well; he detested black Cubans. I remember seeing a young black woman in Chicago wearing a Che sweatshirt; I brought up Che’s past racist rants which he wrote in books. She had no idea; part of the problem with American education.
Its always great fun “introducing” Leftists to their heroes. Be it Che or Marx or Lincoln. Just bring up some of those flamingly racist quotes and hit ‘em with it. Its like a slap across the face for them. Then they have to choose between what they consider the greatest sin - racism - and their Leftist heroes.
and maybe.....just maybe....you can get them to actually start to THINK FOR THEMSELVES for the first time....as in “how come I never heard that before? What else have I not been told by my Leftist teachers?”
