This is an odious stand, but it's a stand! I might interpret Obama's evasiveness as leaving it possible he thinks Singer didnt go far enough. Indeed, coupled with his troubling opposition to the Born Alive Infant Protection act, he actually is in line with Singer. That is, it appears he doesnt believe has begun even at birth!
There is so much more proof for life beginning at conception than there is that it began 4 billion years ago.
A liberal will ignore the proof of the obvious, but go to his death defending the idiotic.
