Everyone has a right to choose what to do or not do to their body right?

Well what about the baby's body?

Are you saying "That's not a baby" or "It's not alive" or even "It's not a human"?

But at 6 weeks, it has a beating heart. It is therefore a living being. A human being.

So does it not have a right to live? Someone else can decide if it lives or dies?

What gives someone else the right to decide that? No one has the right to decide life or death over any other human.

What makes it different when it concerns a baby? The most vulnerable humans who cannot defend themselves and have no voice.

Are you saying the baby is not a "human"? So no human rights in this case?
