"I think that people are failing to realise what it means when they say that 7 in 10 agree with assisted dying. It means they agree with the elderly, the disabled, the mentally ill, basically the vulnerable being euthanised. Because that is absolutely where this will end. 100%."
No, the polls do not show that. 7 out of 10 people support assisted dying in some form. What you're saying is like saying everyone who supports abortion supports it in every form and at every stage of pregnancy. That is blatantly untrue.
"Although I presume that we will now no longer need funding for suicide support after this"
Suicide support is for people in mental health crisis or struggling massively with circumstances. That is very different to the assisted dying bill which is for people with capacity, who are terminally ill and who repeatedly wish to die over several weeks. None of that applies to people who are in mental health crisis and actively suicidal.
"What’s that they say? Better a week too soon than a day too late?"
That saying is typically used for people who have to decide when to put their pet to sleep. That is very different to assisted dying as 1) it's an animal who cannot understand why they are in pain, and 2) the owner is making the decision on behalf of their pet. In the bill it is the decision of the person who is terminally ill whether to use assisted dying, they can weigh up their own quality of life and make their own decision.
