The catcalling tied her disability into the phrasing of what the men said to her. That is why I mentioned it because it wasn't "normal" catcalling.

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.
