The arguments seem very low level from the Pro point of view, It's basically 'Have you seen a relative die in agonising pain?' and I totally agree that in such cases assisted dying/suicide should be an option. The anti point of view - mine - is that this is a Trojan horse for euthanasia and intended to be, I find the whole thing sinister in the same way the families found Gosport's deaths 'sinister', the thousands of care home elderly placed on DNR during lockdown sinister, the same way I found my sister and my daily visits to give my elderly mother drink in a care home sinister once I figured out what was actually going on - namely, she'd been subject to passive euthanasia and neither she nor us had any say in it. Adult social care in this country is poisonous and the CQC and the NMC are wholly corrupt, the police too will not investigate this kind of thing, it stinks.
It is against that background that the Assisted Dying Bill with its lack of safeguards is passed. MPs and the public have been played.
As with Brexit, which also passed with a slim margin, the actual motives behind it are shadowy and it is sold on a false premise, also as with Brexit there will be buyer's remorse but once it is done it will be the elephant in the room, discussion will be taboo, as the press can't reveal what is going on even now.
