No, this is just not true. I am telling you this makes no difference at all, it doesn't matter if the fetus is just a collection of cells or a human life. No being has the right to use another human being as a life support system.
There is a famous thought experiment that illustrates this point.
The famous violinist is a thought experiment that aims to test the moral claims around abortion, by applying them in a different context.

Imagine you wake up one day in a strange room and you have no idea where you are, you discover you have tubes coming out of your body and attached to another person in the bed next to you. Some doctors come into the room and explain to you that they are part of a secret music lovers society and the person in the bed next to you is a virtuoso violinist. The violist has a horrible medical condition and will die unless you stay here attached to her. In all the world only you and your specific body can save her.
Are you morally obligated to stay there for nine months to save her life? Notice in this though experiment there is no doubt, no question that the violinist is a human life. We can add that the violinist is also innocent, she was taken by the secret music society just as you were and has been unconscious the whole time.
You can also consider if it makes any difference whether this procedure will harm you or risk your life, and you can consider the odds that this procedure has of working or failing. This are factors you can consider as to whether or not you decide to stay or detach yourself. As you consider your
choice. But the real question is should you have a
choice.
Do you have the right to decide for yourself if you want to stay hooked up to the violinist, or should that decision be forced on you by the government (or the secret society of music lovers.
