Life isn't valuable because of what it might accomplish before it ends. Life is valuable intrinsically. A homeless schizophrenic is worth fighting for. Cluttering the issue with political, racial, or even religious values is dishonest.

It's not dishonest IMHO. 
Seen Rosemary's Baby? Well you just pointed out why it's potential political message was bogus. Life is valuable intrinsically. I wouldn't mind if Satan was aborted, but there wasn't a way to know that would happen, hypothetically, in real life. 
After all, we could just go ahead and abort the Messiah too, then we'd just have the Devil left. 

Life is valuable, and that's the ad's message. I don't know what their intentions were, but that is an obvious conclusion for me to make.
