 Libertine pornography was a subversive social commentary and often targeted the Catholic Church and general attitudes of sexual repression.The market for the mass-produced, inexpensive pamphlets soon became the bourgeoisie, making the upper class worry, as in England, that the morals of the lower class and weak-minded would be corrupted since women, slaves and the uneducated were seen as especially vulnerable during that time.The stories and illustrations (sold in the galleries of the Palais Royal, along with the services of prostitutes) were often anti-clerical and full of misbehaving priests, monks and nuns, a tradition that in French pornography continued into the 20th century.
