I simply fear that the euthanazia mindset inevitably proceeds from right-to-die, to duty-to-die, and I don't think that's right. You make good points though. And I went through this with my mother, that's why it's personal to me.
Sorry to hear about you mother - my wife and I have been through three of these, both in-laws and my father, and it's never easy.
