I was recently reading this section of the Catechism on pornography, and the bolded line stuck out to me:
2354 Pornography consists in removing real or simulated sexual acts from the intimacy of the partners, in order to display them deliberately to third parties. It offends against chastity because it perverts the conjugal act, the intimate giving of spouses to each other. It does grave injury to the dignity of its participants (actors, vendors, the public), since each one becomes an object of base pleasure and illicit profit for others. It immerses all who are involved in the illusion of a fantasy world. It is a grave offense. Civil authorities should prevent the production and distribution of pornographic materials.
I have noticed a tendency of bishops also to legally oppose same sex marriage in the United States and also encourage the laity to do so. This brings me to ask, is libertarianism incompatible with the Catechism of the Catholic Church? Libertarianism basically says that the government should not legislate personal moral beliefs beyond basically protecting human rights (this could also include the rights of the unborn, and there are pro-life libertarians). A libertarian Catholic would typically say that we should be personally opposed to pornography and same sex marriage and should be vocal about it but should not support legislation that enforces these views. I have held this view myself. But is this even compatible with the teachings of the Catholic Church?
