How many people in this fight are personally dis/differently-abled or personally have dis/differently-abled relatives who expressed a negative opinion of the character's original nature/look versus being white hats out to save people who, as many seem to have posted, don't feel they need or want saving of this kind?

By my count, at least half a dozen of us just in this post alone, plus an unspecified number of friends (I assume you meant to mention them too?) and family.

I've seen pretty similar patterns among the complaints about this elsewhere, too- with similar results. It seems like we only count when we agree with the mainstream/majority opinion; otherwise we're just mentally filed as 'not/not really disabled' and we and anyone standing with us get dismissed as 'white knights'.
