It is human. It could never grow to be a giraffe or an oak tree.
Those two arguments should be all that is required for full protection under the Constitution of th eUnited States. But by demented twisting of the meaning of "person", an unborn baby becomes a "non-person" and therefore somehow it become okay to murder it.
I look forward to the day that the USSC rules that an unborn child is a person and all the empty arguments of the pro-murder crowd are thrown in the crapper and this disgraceful period in our history is closed once and for all.
Are embryos in a freezer alive and human? Should the person who removes the power be charged with murder? Is a brain-dead person worthy of the same protection? I'm asking these questions because I believe that all of humanity should be respected and I don't think we can protect entities without essential human qualities without diminishing or even losing that respect.
In my opinion the qualities of human form and human thought (or at least the beginnings of human thought) should be protected.
