@oralloy,
I'm sorry, I cannot find the exact wording in the link that suggests Biden will violate the rights of disabled people.
In another section of his site, Biden wants to ensure disabled Americans are treated fairly.
"Biden will work with the disability community to build a stronger, more expansive middle class so that everyone—regardless of race, gender, religion, sexual orientation, or disability—can find a place. That means amending our laws, policies, and culture to ensure full inclusion of the 61 million individuals with disabilities in the United States in all parts of our society.
Biden will prioritize enacting and implementing policies that break down the barriers to access for people with disabilities living and succeeding in their chosen communities, which means good jobs in competitive, integrated employment; affordable, accessible, and integrated housing; accessible and affordable transportation; inclusive voting processes; and any needed long-term services and supports."
