Eh… A Human fetus is human, but it is not “a human”. Your toenail clipping are human.

Plus, the humanity or personhood of a fetus doesn’t really matter for the pro-choice position. Simply put, there is no (other) legal situation that can compell you to give up your bodily autonomy.

Example. I can shoot someone in the street in cold blood, and they could die without a blood transfusion. The courts cannot compell me to do something as harmless as donating blood to save that person’s life. A fetus, despite arguably being a person, does not have a right to your blood, your breath, your nutrients, or a space inside your body. Full stop.
