You as a naysayer would point out that skins,organ and others cells would be murder as well.
Unfortunatly they are not humans they are part of humans.
A Zygote hower is the smallest of all humans which takes its form as a cell.
Even then you will retreat behind the lines of "It's a womens choice"
Indeed it is but the choice was made at the point of procreation (Sex).
Therefor it justifies as murder on the fact is it human and it is living.
We are talking about consensual sex.
Now redraw your lines again and hide behind more misinformation.
I have said it before and will say it again if you do not want to get pregnant do not have sex.
