I’m not dividing anyone - Disney has. Severity doesn’t factor into that. By not factoring severity for, say, developmental disabilities it avoids uncomfortable and inappropriate discussions. Frankly, it’s offensive, like people who discredit how severe a type of form of autism is, or those who weigh in on how debilitating a form of Down Syndrome may be. If it’s a developmental disability, I have no objection to DAS eligibility.
I’m confused by your “medical documentation showing they need DAS” suggestion. Is there a “I need DAS” form that the AMA or the AAP has promulgated? What I or you or anyone else feels is necessary is irrelevant. Only Disney gets to decide who, or what categories, suffice for DAS eligibility. “_____ needs it” is subjective and may not be reasonable under the law. If Disney chooses to make exceptions for various physical disabilities to the point their existing accommodations are insufficient, that’s on them.
