My argument is basically this:
If you're crazy, disabled but not seriously (say, an unmedicatible sleep disorder) and chronically homeless, and you're depressed unto suicide only because of how you basically cannot survive without access to social safety nets and maybe (like me) the last of those has ejected you, right? Like, let's start with "basically Altered".
You can't be coerced, but maybe your healthcare provider mentions it as an option. Right?
Then take someone who is basically all the above, but they have social safety net access still and, let's see, they're a cis dude. And maybe the provider doesn't mention it as an option.
The basically-me ends up at least CONSIDERING it, the other guy might not even realize it's an option, depending how much of a hermit he is.
Because doctors are even allowed to bring it up unprompted, it creates an imbalance that is able to be put to the use of eugenics. A shitty doctor could get away with soft-balling the option at patients they think Aren't Good Enough and maybe being reluctant to patients they see as Their Kind, forever. And maybe you have 90% of the people it's brought up to say no -- you still have a 10% imbalance aimed at the targets of doctoral bigotry. And bigotry isn't uniform, it doesn't fall everywhere equally. In Canada especially, that's going to come down on indigenous people hard.
Now, for the trans thing.
It's not that it IS targeting trans people. It's that there is a concerted effort to normalize calling LGBT identities mental illness in the US, and Canada (much as they would like to believe otherwise) seems to have a bad habit of picking up our right-wing crazy lately. So this goes through in March, and then the bigots find a way to push LGBT identity onto mental illness lists. And now LGBT people who are vulnerable (which is more common there then in the general population) have doctors recommending MAID to them. Again, say 90% say no -- that's, again, still a 10% imbalance and a SIGNIFICANT impact to the self-worth of the survivors. It still averages out to eugenics.
MAID could be implemented in a way where the patient has to request the information first. That would be much better than this, because this is inevitably subject to societal biases.
