I am pro choice from a legal point of view..
But yes, abortion is taking a life.
When else does life begin other than conception?
All other definitions are arbitrary, political, fashion, not science.
Life begins at the conception of that life.
Not because the bible says so, but because that is just basic biology.
I am pro choice because I think there are ethical reasons to end life.
This too is basic biology. All life is fuelled on taking other life.
Though one does not have to premise it on basic biology. One can find a higher human ethical response to taking a life.
Such as self preservation, which can be the case with abortion, mental or emotional self preservation.
That the health and life the born and established being known as the potential mother outweighs the unevolved foetus if the two come into conflict.
This too can be seen both in ethical and biological terms as an ethical imperative.
But saying it is not killing a life, does injustice to the ethical and utilitarian gravity of the decision to end that life.
Saying it is not a life, reveals a form of ethical cowardace before the gravity of having to take that life.
Such is almost a guilty plea before the woman's own conscience.
