Loosening my pro choice stance.

[Neo-Scholastic]

So if we ever developed human cloning, would you change your position so that every single shed human cell is included in your ardent forced-birtherism?

No. I am using the word 'potential' in the Scholastic sense, as in the inherent potency of a thing that is part of that thing's essence. An active intervention would be required in order for shed cells to gain the essential quality of humanity. Prior to the any such intervention the cells would not have that potency as part of their being.

To say “forced birth” is akin to saying that preventing a teenage suicide is “forced-aging”. Its fundamentally dishonest. The interventions that discourage abortions stop an act of violence against a vulnerable human being. You can debate the merits of discouraging that violence or allowing it to occur, but you cannot define it away with Orwellian double-speak.

Or is your care for potential for human life selective and arbitrary?

No, but yours is and you seem not to care. You are a complete hypocrite. Name one justification for abortion that could not also justify infanticide.

...current cloning technology fully includes implanting embryos so that they naturally develop, after coming from genetic material.

It does not matter how the process starts. The issue is how you justify stopping a process that is already underway.

As I said the point of the OP seems to be that any such justifications for abortion must be made with appeals to pragmatic and political considerations and not biological facts or the ontological status of very young human beings.
