Let's start with the basics. You need life to exercise any of your basic rights as a human being.
What is more important? A person’s ‘right to body autonomy’ or the same person’s ‘right to life?’
A person can live without body autonomy, one cannot have bodily autonomy without being alive.
Therefore, the right to life supersedes the right to bodily autonomy. Fetuses are people, and pregnant people are people. All people are equal.
Thus, a fetus’s right to life is equal to its mother’s right to life. Therefore, the fetus’s right to life supersedes the mother’s right to bodily autonomy.
Every human has the same human rights, the third one according to the United Nations is The Right To Life. You can check out more here. 👉www.youthforhumanrights.org and http://www.un.org/en/rights/.
