those are things defind by humans
so people before we had a SS# and calendar were not "human" to you?
you see the point is where do you draw the line
i draw it at conception
i'd even grant you can draw the line when the ovum is implanted, allowing drugs to prevent that from happening
but we've seen what happens when goverment get to decide
so we had Jews, Gays, Gypsys, Native Americans, Blacks all called non-human by goverment
is that were you want a civil society to be?
