Question: how to reverse the trend?
The trend is already reversing. The sex-for-sex's-sake crowd who scrambles out of doors and windows when the societal consequences of their actions are discussed are graciously removing themselves from the gene pool. Population growth rates throughout the developed world are falling precipitously and are being replaced by people's with more "repressive" sexual moralities. The populations of most European nations (all but Albania) would be declining if it were not for (a primarily Muslim) immigration. The U.S. is beginning to follow the same trend with predominately Hispanic immigration. In a few generations this problem should take care of itself.
