Never
None of the presented justifications are sufficient.
Note: The way that this branch of the debate map is structured essentially makes 'never' the default position. All the issues that might be discussed under this node, such as at what stage a conceptus is a child, and when it is, how their rights are to be weighed against those of their mother, are explored elsewhere on the branch. Putting content under this node therefore merely duplicates existing content; however, the node itself is retained to allow this Position to be rated.
