This happens to people without disabilities quite often too
> one guy on the train pointed at her and told her to kill herself
a homeless person? I don't think these anecdotes are really representative of anything specific to the disability, this has become commonplace in large cities.
Even if the guy who yelled the KYS comment was a homeless person, clearly not every homeless person does that. I saw the guy walk past dozens of people on the train. When he saw my fellow student in the wheelchair, he stopped in his tracks and turned around to single her out and point when he said it. And these anecdotes do not outweigh the other issues with accessibility myself and others in this thread are noting, particularly how public transportation is lacking in accessibility. I think they serve to show broader negative attitudes toward the disabled that come to the surface.
