I'd argue that you are ignoring the distinction that Adams (who I normally find surprisingly shallow) manages to keep in mind:
"I'm okay with any citizen who opposes doctor-assisted suicide on moral or practical grounds. But if you have acted on that thought, such as basing a vote on it, I would like you to die a slow, horrible death too."
He disagrees with; but holds the vitriol, for people who disagree with him; but does not hold the vitriol for people who have actually acted to impose upon others their position.
No, I am not ignoring the distinction because I find it idiotic. Basically, he is saying that he doesn't wish death on you for disagreeing but for having the gall to actually act on your convictions. That is plain stupid and infantile. And this is coming from someone who agrees that we need euthanization laws.
