To put the abortion matter simply, it comes down to the root of morality – survival. Personal survival and survival of the species. In the case of abortion, there are two people who are significantly affected in their ability to survive directly, plus there are indirect issues that pose risks to elements of humanity to a much lesser extent, but a significance nonetheless.
In saying that, there is no argument to close the case as to what is the best course of action when it comes to abortion. Every view is a matter of opinion. Chances are this subject will continue to be an argument going forward for the foreseeable future. We should learn to understand and respect each other’s opinions as really, both sides are pro-humanity, just from different angles.
