As someone who has worked a lot in disabled rights, I take serious issue with some fringe groups, like those that oppose cochlear implants for children on the idea that it is cultural genocide against deaf culture. I appreciate that people want to take pride in their identity, but people make cultural decisions for their children all the time—it's part of being a parent. So is providing your children with the best opportunity to succeed in life, and cochlear implants help them do that. It's great that many people with disabilities are able to carve out an identity and culture that they're proud of, but they don't get to dictate that others remain part of it.
That said, I don't see this as an example of that. I don't see people asking that her career be finished, or that she raked over the coals. They're expressing how hearing that somebody is better off dead because he no longer has the disability they have makes them feel. Being accosted with the attitude that you'd be better off dead, day after day, is not something you get used to, and it's not something you should have to. Educating people about how that makes you feel is perfectly fine, in my opinion.
