This blogpost from Paul Russell addresses Australia’s most recent euthanasia-related controversy:

Russell states that tolerance of any suicide sends a very mixed message such that, “Suicide should be prevented, except, perhaps, you know, when you’re really ill or dying; or maybe when you’re very old; or maybe when disability makes your life really difficult. But once we create these kind of implicit exceptions we also tolerate a double standard… We’re effectively saying to the old, the sick, the disabled etc. that they’re somehow less worthy of life than the troubled teen.”
