Well as a retard myself (seriously, not kidding around), I would say yes. Down Syndrome or any other condition similar to it results in a most unfortunate life. The worst part is it leave you kind of scared to commit suicide, so you're kind of trapped. People automatically want nothing to do with you, and the few that do usually wanna goof on you or take advantage of you. This for me has resulted in a state of almost paranoid schizophrenia, I can't even leave my place.

So in my opinion it is selfish as F*, to not abort a retarded person. you're putting them in a world that wants nothing to do with them, and they are evolutionary dead ends. Do the fetus a favor, and flush it. Wish they'd done that with me.
