In my "ideal" world I wouldn't have to see the hellfire and damnation billboards, or the infamous Uncle Sam billboard when going up I5 (or any billboard for that matter, visual blights that they are), but there's that freedom of speech thing.
But to be fair, from my POV most religions are based on a mythological element (I say "most" because I'm not familiar with all), and I think most Christians would, if pressed, agree with that terminology, particularly when talking about polytheistic religions. I don't see "myth" as negative -- after all, it's broader definition often explicitly includes religious tradition -- although I readily concede that some do. This is where Bill would come in and rail against the definition of "myth" as a generic term for a false belief. :)
