Mulims had it figured out long ago. Marry, marry, marry, and have kids lots of them, have even four wives if you can, and this way they can over populate the world, and this is exactly what they are doing. Other countries have been told by their own governments that the world is getting over populated, and so what do we do? We have less children, while undesirables come into our county and try to destroy the American way of life.
We will be the losers if we do not honor marriage. Same sex marriage only insures our destruction, and our sure path to Sodom. We will deserve what ever comes to us, and it surely will.
People don't have fewer children because the government tells them the world is getting overpopulated. They do so because they have economic freedom and they value their own happiness (however they define it). The only difference between now and before is that now people are free (have choices). BTW, who do you consider to be "undesirables?"
