To abort or not to abort

[Chas]

Moral protection means society has an obligation to protect that being from deliberately being harmed by another being. Abortion is an act which deliberately harms another being. Its black and white.

The obligation to protect a being from unintentional harm is not black and white. You don't have an obligation to save the child that fell into the path of an on coming train if doing so means sacrificing your own life. Now you may choose to put your life in jeopardy to save your son and not choose to put your life in jeopardy to save a zygote. The reason is because you value your son more than a zygote.

It may be black and white to you, but only if you believe that a bundle of cells without a brain or nervous system is a 'being'.
I'd say that is hard to justify.
