I never advocated locking up anything. You failed to prove that a few posts ago, yet you're so thoroughly defeated that you went back to that anyway.
Once again, my argument is, was, and always has been that the act of "abortion" is unethical, not that anyone should initiate force against someone else. The birth process is a passive one, and in the absence of force, will be completed. This means that the active position is the termination of that child, putting the burden of proof on the one seeking to terminate it.
Secondly, the first section of your post is completely nonsensical. All humans are self-owning agents, they therefor own themselves, and have the same rights. Geographical location of a person or object does not put them under the ownership of someone else, and one agent cannot own another without the agent's expressed consent, when they are developed enough to do so. Because an unborn child is incapable of giving consent, implicit consent does not exist, and the child is a self-owning agent, the mother cannot own the child. It is therefor the child's decision regarding what is done with its own life. Saying the child does not own itself is, therefor, special pleading.
