Roe v. Wade is gone.

[Angrboda]

They have the potential to become something.  Arguing that simply because something has a potential to become something that they should be treated as the completed thing is no less devoid of facts.

I would say that sperm is what has reproductive potential, and conception is the tipping point that transforms that potential into the developing organism.

Now, when I use the phrase developing organism, I don't mean that the end result of that development is the emergence of the organism. What I mean is that the organism itself has begun to pass through stages of development. So I agree with you, but the potential we should be talking about isn't whether one stage of development can reach another stage, it's whether any of those stages precedes the organism.

All preceding stages precede the organism back to the beginning of time. You are simply doubling down on treating it as all one thing or the other. Like I said, rather than acknowledge nuance, some prefer to insist on black & white thinking.
