In a society where political factions were not wooing the other side for sexual lifestyle votes, pornography would decrease. That's another way of saying that pornography eroticizes power by creating good sex and bad sex--a basis for faction. There is no solution to pornography within imperialism, because there is no way to eliminate profits from the entertainment industry and pandering for votes in the politician business. As long as there is a possible gain from talking about good sex and bad sex, there will be entertainers and politicians taking advantage. To crush pornography requires a monolithic political will--a friendly unity that is difficult to envision right now.
The elimination of the two party system and the profit-run economy will take most of the wind out of the sails of pornography. Without sickly competitive pluralism, pornography cannot flourish. If there were not imperialist factions, the imperialists would not have bothered with Monica Lewinsky. Ultimately, we cannot expect pornography to disappear in class society. The best we can do is restrict pornography under the joint dictatorship of the proletariat of the oppressed nations, while we work on eliminating the underlying causes of political faction formation in the formation of classes. When money, state power and the various forms of power coming to bear on sex are gone, pornography may also be gone. If not we will have to keep refining our theory of the patriarchy and gender aristocracy until we get it right.
