It's Apples v Oranges, because those are Models w/ Down's Hired to pose for (anti-Eugenics) Ads... it's pretty much 100% "Please, Don't kill Down's Babies." and has the Statistics(one assumes correct ones since you're not attacking their Numbers)
Little Corky McDowns isn't standing up at the UN talking about "I love my Mommy & Daddy, I'm so happy I didn't get aborted." or "I was supposed to have a Cousin, but when my Aunt found out he'd be like me, she had him aborted."
Apples to Apples is: if/when Corky makes his speech and You say 'Corky's Wrong' and 'our' only defense is "Leave Corky Alone!!!, he's got Down's."
