It comes from a Facebook meme page called “The Ghost of Ol Dale Earnhardt”. The creator said he was frustrated with alt-right people posting fake quotes on pictures of Southerners that made them seem like facists, so he decided to post fake quotes on a Southerner that make him seem like a communist.
I find it weird, but Americans love claiming that dead people support their cause. Like how Martin Luther King is both a progressive and conservative icon depending on who you ask. Same with the founding fathers.
