Reading the original article, it seems that it deals more with the modern West's view on abortion rather than directly discussing the ELCA's social statement concerning abortion. So, in the context of the Left-hand Kingdom...Here's my take.
I'm in favor of the reversal of Roe V. Wade. I'm also not going to hold my breath. I also think that the concept of "Freedom of Choice" is so firmly ingrained in the minds of my generation (x) that support for an abortion ban amendment gets less likely as the years go by. I see banning abortion as being a "supply-side" approach to the issue. If abortion is banned, women will still seek abortions (just like people continue to willingly commit any other crime). With the "right to choice" tending to be firmly entrenched in the minds of those of childbearing age, I think it would become the medical equivalent to Prohibition. That's where the second approach comes in.
The more difficult approach is what I consider the "demand side". There are things that we know reduce the numbers of abortions. A strong economy helps (less abortions based on dollar and cent decisions). Also, unwed mothers should be considered people who should be helped rather than viewed with disdain. The adoption system should have the kinks worked out of it. People need to work on understanding birth control and how it relates to sex and procreation. As a member of a post-sexual-revolution generation, my personal observation is that people tend not to draw the conclusion that reproduction is the natural outcome of sex; which I think is ridiculous from any logical standpoint. Rather, procreation is seen as something that happens when it is planned.
The biggest challenge that I see, though, is changing the way people view human life. The value of human life needs to be extended to all human lives, and this includes the lives of the unborn, the mentally retarded, the homeless, etc... In our various congregations, I'd imagine that all of us in various ways try to inculcate this way of thinking. However, it extends far beyond the extent of Lutheranism and Christianity; it's American Culture in general. That's a big part of why it's such a difficult problem to fix.
