I think it seems to usually be more about disabled people, who ai bros tend to consider either too stupid or physically unable to make real art, which is bullshit. There are amputees painting with their feet, who knows how many artists who have prosthetic hands or chronic pain. And don't even get me started on mentally disabled people.
I'm sure all disabled people love hearing "Oh this other disabled guy showed extraordinary willpower and overcame his disability against all odds why can't you"
The game Katawa Shoujo, which was actually made by a cooperation between people who were on 4chan, depicts amputees and disabled folk, one of which is an artist which draws with her feet, with many of them having traumatic experiences that you hear of as you get to know of them more personally
