Europeans, especially nordic countries, are well down this slippery slope. Iceland iirc has no Downs population left due to pervasive abortion practice.
In contrast I know people who refused the prenatal test on the grounds that they wouldn’t be considering abortion regardless, so the results would be irrelevant. I also know people who have a Downs child and consider him to be a great blessing.
People who decide to abort a Downs syndrome child are foolish because these children are a blessing and just as wonderful as any child. I have a Downs niece and she is pure sunshine in today’s world. I wouldn’t trade her for any other person in the world.
