One's personal stand on abortion or on anything is no one's business. But when one proposes to impose on others, one's arguments must be based solely on reason and reality.
There are no rights other than Individual Rights. The power of any government, state or federal, comes from the people, which cannot delegate a right they do not possess. In freedom, the only right delegated is the right to self defense (except in case of an emergency), so that citizens deal with each other only by reason and persuasion, never by force. Abortion is a matter of rights, not subject to resolution by each state.
Arguments against abortion that are not based on science, i.e. reality, are theocratic and/or tyrannical. Only an actual living rational being has rights. One cannot reason with animals, so they do not have rights though they have life and brains. By nature, man is fallible, so a woman may get pregnant though she and her partner might not yet be ready to be parents. The question that must be resolved based on science is when the unborn human being acquires rights, and thus becomes equal to the mother when it comes to rights.
I use the criterion for the cessation of human life, brain activity, as the criterion for the onset of becoming an actual living rational being. Only a being with a rational tool can be considered human, thus the zygote or embryo, though has the potential to become human, is not yet an actual human.
A fetus has a central nervous system and brain activity. Thus, it is an actual living rational being. Hence, it has rights.
