I think of the abortion issue as like a necker cube. You can view the optical illusion as extending inward or outward. But it is difficult to see it both ways. You could easily see it as flat, but then you aren't really seeing it at all.
Partisans may object "but in the abortion case it is objectively extending inward and the other perspective is the optical illusion". But that objectivity is a moral illusion.
