Will Saletan makes the connection:
I always thought Kevorkian was basically right about assisted suicide. I figured that if my parents ever wanted to end their lives, I'd find the pills and help them. … Assisted suicide, it turns out, is a lot like abortion. No government can stop it—I would have risked jail to get the pills if necessary—and efforts to enforce its prohibition only make it less careful and humane. But, like the right to abortion, it can be abused. People want to die for all sorts of reasons. Sometimes it’s agony. Sometimes it’s boredom. Sometimes it’s fear. Maybe your mother needs a lethal prescription. Maybe she needs antidepressants. Maybe you just need to hold her hand.
Douthat complicates the analogy.
