In this moving article, Alex Schadenberg gives a penetrating analysis of how the recent B.C. Supreme Court ruling on a person's right to assisted suicide is not, when seen from the perspective of a disabled person, an expression of compassion. Rather it reflects deep-seated discriminatory attitudes toward the disabled.

The bottom line of the argument: 
To put it simply, if a non-disabled person wants to commit suicide, she’s considered irrational and mentally ill, and is treated for depression, or maybe even locked up to prevent her from hurting herself. 
But if a disabled person wants to kill herself, she’s told she’s making a reasonable choice, and not only has the right to do so, but is even helped to complete the act so her death is guaranteed where most other suicide attempts fail.
That sounds like discrimination to me.
