"I am an optimist."

"I am a realist."

Any "optimism" that requires an abandonment of reality is not being optimistic, but delusional.

There are many, MANY people who would 'select" a baby with blue eyes -- by dumping the ones with brown eyes.

You know many people are currently aborting female babies in countries where couples are limited to one or two babies.

You think people wouldn't de-select babies who were going to be Autistic, or gay, or sub-cute or any other quality the parents didn't want?

Many people have babies as a life-style accessory. They'd have them in colors to match their  cars if it were possible.
