The Morality of Abortion

I hear them telling me that Abortion is the right a women has over her body.

I hear them saying its not murder.

I hear them tell me they are not even humans.

I hear them tell me that they do not have rights for they are not "peoples"

I hear them tell me that Abortion is a good form of population control.

If this is not a human, or a person, and this is not murder...than what is it?
