The downtown Cincinnati billboard reading "Don’t Believe In God? You are not alone" is moving locations. The billboard is run by Lamar Advertising, but this particular billboard is on private property leased by Lamar. Apparently the landowner has "received multiple, significant threats" either to property, person, or both.
In my opinion, even with the vagueness of the statement, these are clearly threats of terrorism. Who else in an area like that, would threaten a message like that, besides Christians?
If I was that landowner, I'd be calling the police, FBI, and or Homeland Security. But then again, maybe the landowner didn't like the billboard, so made up the threats. Any-which-way, this is a form of terrorism aimed at non-believers, most likely originating from Christians.
Shawn Jeffers, co-coordinator for Cin CoR (Cincinnati Coalition of Reason) said "Everything that has happened shows just how vital our message is. It proves our point, that bigotry against people who don’t believe in a god is still very real in America. Only when we atheists, agnostics and humanists come together and go public about our views will people have a chance to learn that we too are part of the community and deserve respect."
The United Coalition of Reason has now funded fourteen campaigns this year.
