“That’s not a human unless I say it is a human,” is an argument used by those who have practiced genocide throughout history.
The Nazis used the argument to exterminate Jews. 19th century American slave owners used the argument to enslave and kill Africans. The Romans used it as they wiped out populates. Communists have used the argument throughout the twenieth century.
It is also the argument of the American abortion rights activist. A human is a human regardless of its stage of development. Whether within or outside the womb, a human is a human. Even in the grave, a human is a human. We know these things because of science. To deny a person is a human is to degrade humanity. It is to separate some into something other than human.
It is what Christine Quinn does on CNN with an assist from CNN anchor Chris Cuomo. Everyone should be appalled by it. But some will defend it and cheer her on. Claiming “it’s my body” is no different from the slave owner claiming “it’s my property” and claiming “it’s not a human” is an argument that always ends badly for a large segment of humanity.
