The hell do you think you’re going to learn by asking other ignorant people?
If you want to understand what it is like to have a given disability, search out materials written by and for people who have experienced those disabilities. If you get a chance to ask a disabled person about how that disability affects them, without being a boring, insensitive, dehumanising dickhead, do so.
Don’t ask a bunch of people without those disabilities to debate which would be most awful. And do not pretend it’s about educating yourself when you’re addressing your question to people who are mostly as clueless as you are. You’re not going to learn anything useful at all and you can’t possibly have imagined you would. You’re just adding to the mountains of awful dehumanising bullshit that is already out there.
