Tension often exists between political freedom, particularly freedom of speech, and certain examples of art, literature, speech or other acts which some consider to be sacrilegious or blasphemous. The extent to which this tension has not been resolved is manifested in numerous instances of controversy and conflict around the world. Although many laws prohibiting blasphemy have long been repealed, particularly in the West, they remain in place in some countries and other jurisdictions (see Blasphemy laws). In some cases such laws are still on the books, but are no longer actively enforced.
