All you have to know about Leftists and their attempts to “cleanse” American history of “badthink” is the worship that so many of them have for Castro’s hangman Che Guevara.
The campaign to push most of American history down a memory hole is truly absurd, since the past remains the past. Of course all this is being done for political ends, often by truly evil people who reveal to us the type of society they would bring about by the “heroes” they celebrate. Only idiots take moral instruction from these villains.
