> Not donating bone marrow requires doing nothing. Having an abortion require an active procedure.
True, but simply not relevant to any point I made. No metaphor is perfect, but the point here is that your control over your own body trumps another right to life. You wouldn't allow the government to forcibly take your bone marrow to save a life, and that's no different than being forced to carry a pregnancy to term against your will in regards to the point of bodily autonomy. Another persons right to life ends when it depends on someone else's body to live. The other person has a right to not consent to use their body against their will.

I think you need to refine that stance.
As a parent, I certainly don't have control over my own body. If I fail to provide the necessities of life for my child, I will go to jail and my kid will be taken from me. The gov't can (and will) force me to do certain things with my body.
Child neglect has nothing to do with your body. You are free to give up your child for adoption if you don't want to take care of them. Abusing a child and being punished for it isn't remotely similar to anything being discussed here. You're yet again deflecting from the point and attempting to setup a strawman.
