Yikes! This is what you think of the human fetus? No wonder we can't get anywhere with you. Religious principles aside, most Western philosophers and ideologs see an intrinsic superior value of the human mind over all other things in the known universe. You see the developing human mind as of no more importance that a virus. Communications.......out.

It is still the case that we do, and should, allow people into the moral community as they demonstrate the capacity to exercise moral judgement. No other criteria makes sense, or allows cultures to persist. Rights for cows was tried and failed by the Indus valley civilization.
