Can we cite the folks leaving religious tracts at bus stops and hotel lobbies for littering?
"Freedom of religion" cuts both ways; don't push for regulations that will come back to haunt you later.
Oh yeah? Tell that to the Christians who can't speak their minds in public, or where teeshirts with anti-abortion message or pray without some namby-pamby or activist judge shuting them up at every turn!
There is an active process in the world to shut Chirstians up, because men love darkness rather than light, haven't you heard?
