What's Orwellian about it? You have to admit that at some point during the natal development cycle, there is a completely viable child in there capable of growing independent of the womb.

How is that not an unborn child?

The overwhelming majority of abortions are performed well before this point is reached.

Thank you for demonstrating the Orwellian nature of this phrasing.

The problem is that you are arguing like all of them are.

By unconditionally accepting this you are defending some really really questionable practices. The fact that the laws I mentioned above (or below) even had to be made in the first place says something about this.
