In reading the post on feminism, economy and warfare I recognize immediately that I haven't covered much of any salient aspect of sexuality vis a vis birth control and reproductive freedom. So let me cover that here briefly.
It seems to me that the manner in which Tom Lykis approaches sexuality is really appropriate for questions of sexual freedom. And to the extent that I can accept sex as sport I would have to say that it is an amoral sport between consenting adults. I cannot give it any more significance than that of sport. So it is altogether fitting and proper that we consider prostitution as a professional sport.
I imagine an America in which prostitution is legalized as one in which the value of marriage would be increased immensely. But I have no trust whatsoever in the legal establishment with regard to protecting that value through proper regulation of the sex trade or changes in family law in light of the development. I also think that the demand for same-sex marriage would increase as well.
The effects of sexual liberation and reproductive freedom in an America with a healthy market for legalized prostitution would essentially be nullified. Instead of the sub rosa hooking done by various and sundry liberated females with no appetites or prospects for marriage, it would be the new small business boom, a Silicone Valley. The Tom Lykis show, which essentially reflects the conventional wisdom about extramarital sex, when there is any wisdom to be had on the het side of the equation, would be vindicated in full.
And the Sacrament of Holy Matrimony would remain the same, except people would be forced to take it more seriously since all of their 'relationships' would be shown for what they are: amateur sports.
