Very well, yes.
As you say, it would be very discriminatory. If someone meets all the criteria established by the Supreme Court in Carter, I don't see why their request would be treated differently or a decision would be made differently because they have clubbed feet or are missing an arm. That would be discriminatory because it would put another barrier in the way of someone exercising their right to request MAID.
Why should these people, who already have a lot of difficulties in life, be subject to greater requirements than people with cancer who request medical assistance in dying? That would be completely discriminatory.
These people don't need to be protected. They are capable of defending themselves. If we respect their rights, if we respect them as human beings, they will be able to protect themselves. They do not need a good Samaritan to infantilize them or use them as pawns for other purposes. If their rights are respected, people with physical disabilities are able to make decisions by themselves and for themselves.
