At the Illinois Lutherans for Life conference this past Saturday, one of speakers showed the trailer for the Documentary - Demographic Winter. The film deals with population rates and their decline in the West. I picked up a copy, will watch and post a review. The film has been out for about a year now and if you google it you will see that the pro-abort/anti-life side are not fans. The movie's trailer is worth a watch.
At the conference the question was asked if contraception aided the demographic winter as well as the culture of death. The only non-Lutheran presenter, who showed the clip, said yes, and referred to Luther's writings on the subject.
