I appreciate what you’re saying here - people come in all shapes and sizes, with different abilities, limb counts, etc. Every one is a human being deserving respect and dignity.
But OP didn’t say “a complete human being” - it said “a complete human skeleton.”
If an individual is missing a limb, by birth or by accident, they don’t have a complete skeleton. It’s a plain fact. Doesn’t mean they are any less human.
