If that is not a human, then what is it?
If it is a human embryo, then that is a human in the embryonic stage, and as boredmeme stated, if we test its DNA, it could be nothing but human.
Embryo, Zygote, etc. are merely technical terms to define the stage of growth an organism is in; they do NOT define if that organism is worthy of life. You are being very anti-scientific to misuse those terms in this fashion, and just because you find many others doing the same does not make it right.
That was you, before you decided to become an obnoxious, whiny liberal imgflip troll; it was every human being who has ever lived. Because humans in this stage of their growth are murdered behind closed doors, you can afford to look the other way, not unlike how the 1940s German citizens looked the other way as other human beings were shoved into ovens and mass graves.
Just as those German citizens were culpable for voting to put someone in power that was willing to do something like this, and then tried to ignore what was happening, made them no less guilty of being an accessory to murder. This is equally true for all who support abortion.
