As usual, Fred Clark hits the nail on the head:
If [President Bush] truly believed that such [stem-cell] research involved “the taking of innocent human life,” then he would be obligated to stop it using every means at his disposal. “I won’t fund it, but it’s fine if others do,” doesn’t cut it. All such funding, all such research, would have to be outlawed — with severe criminal penalties for the mass-murdering Mengeles who violated this ban. The fertility clinics, also, would have to be shut down. The innocent human lives imprisoned in their liquid-nitrogen charnel houses would have to be made wards of the state until such time as they could all — in their many thousands — be placed into snowflake foster care.
I am not suggesting that this is what President Bush’s position implies taken to its logical extreme. This is what it demands as a bare minimum response. It is not possible, in any meaningful way, to believe that embryonic stem cell research is “the taking of innocent human life” unless you also advocate all of these steps.
President Bush does not advocate any of these steps. If he is not a liar then he is a fool or a monster. There is no fourth option.
