LIKELY RELATED TO A DEFINITION OF "HUMAN" THAT HAS NOTHING TO DO WITH HUMAN BIOLOGY.
Example: "human: adjective -- relating to or characteristic of people or human beings"
NOTE the phrase "human beings" is used as a synonym for "people", even though we all know that entities don't have to have the slightest bit of biological human-ness to qualify as people (True Artificial and/or extratraterrestrial alien intelligences, for example). That
definition gives rise to other related words like "humane" or even "humanity" (
as famously used when the Hindenberg burned/crashed) --but neither one needs to have anything to do with human biology.
AND AGAIN, NOT ASSOCIATED WITH HUMAN BIOLOGY. Only the idiocy of blathering abortion opponents wants folks to conflate definitions, putting human biology in places where it does not belong.
THEN YOU ARE GUILTY OF IDIOTICALLY CONFLATING DEFINITIONS. Especially when you know full well that there are plenty of human entities that neither you nor anyone else will consider granting right-to-life, such as hydatidiform moles, cancer cells, and cuticle cells.
IT IS NOT "QUAINT" --it is purest idiocy. Because not even abortion opponents are stupid enough to claim: "Oh! Cancer cells are human entities! They deserve right-to-life! All research into killing them must be banned!"
YET THE CONCEPT OF "PERSON" IS NOT SO ARBITRARY. It can be as simple as any entity that meets these three conditions:
1. It is able to understand the concept of "rights".
2. It is able to claim rights for self.
3. It is able to accept and respect claims of equivalent rights made by others for themselves.
SEE YOUR NEAREST ROBOT --of today's technological level, that is. Future robots, of course, are likely to be sophisticated enough to qualify as persons per the description above.
WHAT'S WORSE IS THE IDIOCY OF CONFLATING DEFINITIONS. The Stupidly Prejudiced Master Race Idiocy that you blather will in no sense allow you to grant rights to non-humans, simply because you fundamentally base your idiocy on human biology.
