Guys.....isn't this going a bit too far?

[Whateverist]

I think too much is made of arguing the logical consequences of certain generalizations.  When we're discussing how we treat each other, we generally have in mind others like ourselves with the capacity to decide how they shall treat us as well.  To then argue that, well, an embryo is in one phase of becoming a person like ourselves so whatever we decide in regard to others like ourselves should extend to them too requires further argumentation.  It shouldn't be automatic.

Newborns and ppl with mental retardation such as Down Syndrome or anything of the like, don't have "minds like ourselves" either.

True, but that they exist at all is evidence that they matter to someone, someone like us who supports and loves them.  Therefore we have to extend to them the same consideration we do to others like ourselves, just as we expect them to do toward our loved ones.

I'm not saying it isn't valid for someone to feel a zygote is entitled to the same consideration as a person such as ourselves.  I'm just saying it requires more argumentation to a get someone to agree who doesn't feel the same way.
