This is not true, otherwise the nice old man on a pacemaker and oxygen
isn't alive either. He also can't sustain his life without support.

Yes its the human species we are talking about but -- Unborn vs. Born "human beings", but okay.

​

A zygote, an embyro, a fetus, an infant, a toddler, a pre-pubescent, a
teenager, and an adult are all equally living human beings.

Except again, Born vs. Unborn "human beings". An infant/toddler is defined between the stages of birth and puberty.

​

Killing another human being may be the 'best' decision for someone, but I
see no reason to allow such a horrific violation of human rights.

We need to define when these "humans" have rights, as far as I'm aware, this human has no birthdate yet, does it have rights before birth? Does it have a name? Does it have a SSN? How can we give something rights that has no identification to it?

I'm trying to be civil here, but I personally believe that the person with a fully developed brain who may have got pregnant on accident, or raped, or partially developed brain and she's only 16 and has no parents herself, knows whats best for their body and life. We shouldn't bring more children into this world if we're not fit to handle it.

This is an extreme outlier situation, but if you were a woman/girl and you were raped by a psychopath who murdered your family, wouldn't you want the choice to decide whether you have to keep that persons baby or would you just like to be told sorry, you have to go through that on your own or you go to prison for 10 years?
