Obviously for many people it's still very scary - it is death after all. But the self-administered morphine drip has been around for ages and is relatively uncontroversial.
Is it? As an atheist I welcome the nothing; no more worrying about filling out taxes and such. Being religious you really should be jumping for joy (although you cannot kill yourself probably), but how is death scary if you believe in something after?
They care about your relatives who are burdened not “accidentally” holding that button for you when somehow you would still like to live.
Neither of those matter because they don’t hold massive, disproportional influence over a huge part of the US political establishment.
And that's as of 2015, so the trend may be higher by now. https://www.pewresearch.org/short-reads/2015/10/05/californi...
Several in-patients that opted for medical assistance in dying were refused that treatment by administrators of the hospital on religious grounds, and their families are sueing based on the additional suffering inflicted by having to transfer to other facilities.
It’s just not a great hill to die on since most people that actually care strongly about the issue are the ones bed ridden in the hospital.
That’s almost always a financial incentive though; if you remove that you can see who really cares. I have an open will for my friends and family; everything goes to charity with the taxes and tangible assets worked out so they don’t have issues; they get a net amount of a few million. Everyone else knows they don’t get 1 cent; helps with the accidental button holding.
