I'm autistic (a developmental disorder/disability), and that won't change as long as I'm living. Life for me can be difficult at times, and overwhelming at others, but it's not 100% impossible. For me, I get overwhelmed from too much stimulation or from trying to overly control a lot of the disorder's symptoms. The worst for me is auditory over-stimulation, as it's difficult for me to process auditory information, especially at high speeds.
For me to have seen Trump's offensive commentary was a realization of how badly people with disabilities are stigmatized. It makes me also realize just how strongly he may push for the repeal of the Americans with Disabilities Act, which would make life for people like myself much more difficult.
