The left is waaaayyy too formulaic about their hoaxes, which make them appear far too fake than they realize. The KKK is pretty much relegated to the 20th Century, but they still pull out that old, dated race relic to invoke outrage on the left, trying to convince smarter people on the conservative side that they are still victims of a ghost.
That joke is closer to the truth than the leftists at the SPLC will ever admit. Of course, if they officially recognized that the current Klan is a powerless entity peopled almost entirely by undercover government agents interspersed with some deranged sociopaths and few of the trashiest and most powerless of white-trash, they would lose one of their primary fund-raising memes.
