It works because when there’s an A/B binary and a rare anomaly C comes up, it changes nothing about the definitions of A or B.
1. AB and C doesn't describe a
binary system. You listed three items and binary means two.
2. It's telling that you insist male and female are these immutable categories of specific combinations of chromosomes and genitalia and then everyone else (the intersexed), who have a whole host of varying characteristics you lump in together as simply C.
3. Anomaly doesn't mean what you seem to think it means. It doesn't mean a non objective thing we can dismiss as too unimportant to address. If your argument or theory has an anomaly in it that you cant explain the you have a faulty or incomplete theory or argument.
Humans are supposed to have 2 arms. that’s an objective fact.
Its not. When you use words like
supposed to you aren't making an objective statement, you're making one about desire and ultimately emotion. Objectivity is about describing what you see, not what you want or hope to see. You could objectively say humans
generally have two arms but occasionally are born with only one or none. That's an objective statement. It's about math and averages. Humans generally have two arms. That's a completely different statement than humans are
supposed to have two arms.
Humans are also supposed to have a head with a brain in it, 2 legs, a heart, 5 fingers and 5 toes, 2 eyes, 2 ears, a nose, a mouth, etc….That’s the blueprint.
Do you disagree?
Yes, I disagree. What is the objective argument for why this is
supposed to be? That's a religious argument. Its only religion that insists there is a way humans are
supposed to be. The scientific argument is that humans are made up of elements of oxygen, carbon, hydrogen, nitrogen, and calcium that make molecules of proteins, carbohydrates, lipids, and DNA. You are the product of how these elements and molecules arrange themselves, and random mutations and evolution don't stop just because you think this form right here are how humans are
supposed to be. People are born without arms because that's what their blueprints (dna) dictate. If DNA and genes (the blueprints for how you are built) are not the cause of some babies being born without arms, then what is? Magic? Voodoo? Not praying hard enough?
