"I have said repeatedly that it is my opinion that the extension of civil individuality to a zygote is a misapperception"

and that, my friend, is a false dichotomy. There are WAY more abortions performed on fetuses that are developed than there are on "zygotes". You are the one who has simplified the arguement beyond meaning...

...by making the case that because you cannot distinguish a good point of development between zygote and birth, then such a distinguishing is not possible.

And so you comfort yourself with the notion that abortions are performed on zygotes. And call me simple-minded.
