Scientific racism was the rationale for white colonialism. Scientific and medical ableism is similarly used to support MAID for people with disabilities. For example, scientific ableism made it that not long ago, homosexuality was considered a disability. Presumably, we would now be discussing the possibility of MAID for people because they are gay if that hadn't changed.
Today more than 80% of U.S. physicians reported that people with significant disabilities have a worse quality of life. This false assumption is believed to contribute to the health disparity experienced by disabled people.
Medical ableism provides MAID with a false facade of legitimacy and rigour that our suffering can't be mitigated and that we are better off dead.
