It's probably more true if you include disabilities that you may not be considering. Acquired hearing loss, blindness due to retinitis pigmentosa, chronic back pain, etc. I find it very hard to believe that a person who lost their vision in an industrial accident wouldn't leap at a chance to have their vision back. And obviously not all policies to reduce the incidence of disabilities are about eugenics. OSHA isn't a eugenics program. Vitamin K shots and eye ointment for newborns reduce disability without being eugenics. I assume even blind disability activists don't think babies should be put at risk of easily avoidable blindness.
