First, there is lots of good analysis at the beginning, but in the end, the writer’s conclusions do not follow. The only situation that would justify abortion would be when the birth places the life of the mother at a greater risk than is part of the natural birthing process or via any intervention that is safe and effective to provide the birth of this child, such as C-section.
Jews have no right to impose our halakhic law upon the larger society, and no abortion law that I know of imposes an absolute ban when the life of the mother is in immanent danger.
Recently, many Christians have picked up upon the conceptual ties to the current abortion argument and the cult of Molech. This is the appropriate way of framing the issue. Arguing that children should be aborted because they “could” become criminals is wrong. Or arguing that economic opportunity justifies abortion is essentially the very substance of Molech worship.
The issue with abortion is and will always be the issue of birth control. Birth Control fails at a statistically predictable rate. If you have sex out of marriage, the number of opportunities to become pregnant vs. the failure rate creates an increasing envelop of likelyhood that a pregnancy will result. The push for birth control was to create freedom for women to have sexual relationships out of marriage. This is and has been a losing proposition for women (as a whole) since the idea was put forward but a significant minority of women deeply appreciate this freedom and want to maintain it. This is because people just don’t and won’t agree on these things except in the most general way. Abortion restrictions create consequence that drives the equation of consideration so that society once again favors sex within marriage. #MeToo is all about this same issue..
You like secularism? I'm afraid you're not going to enjoy the Messianic era very much.
