It's interesting which people are on which side of the Oregon assisted-suicide issue. Those who are opposed think the federal government should be able to step in, using its anti-drug laws, to keep physicians from participating. Those who favor doctor-aided death want to make it a states' rights issue. But consider the abortion debates attending Roe vs. Wade. Those opposing abortion -- the same people opposing euthanasia -- thought it should have remained a states' rights issue instead of being federalized by the Supreme Court. Those favoring abortion -- the same people favoring euthanisa -- wanted it taken out of states' hands.
Proving that sometimes people just want what they want; life-and-death issues trump bedrock philosophical principles.
