I had a back-and-forth with a Snopes editor over a minor, Obama-related Progressive meme (issue unimportant, not “birth”, PM me if you want details), a complete historical falsehood that the editor rated “Mostly true.” I researched the issue from neutral sources, cited legislation and actual real live history, and the knucklehead was adamant, standing behind the falsehood rather than actual history. Haven’t gone on the snopes site since, save for the linked apology from the plagiarizing founder.
