The Truth-o-Meter says: Pants on Fire! | Viral meme says Islamic group posted threat to kill Americans on sign in Dearborn, Mich. A reader recently sent us a meme circulating on social media that purports to be a threat by radical Muslims to mass-murder Americans. The meme was pasted into an email with the subject line, "A sign in Dearborn, Michigan." (Dearborn has an unusually large Muslim population.) Headlined, "This is what liberalism will buy you," the meme features a photograph of a sign with removable letters, purportedly advertising a group called the Advancement of Islamic Agenda for America.
