It's more complicated than that, I'm afraid.
You don't speak for all disabled people. Some disabled people take pride in their lives.
There is a word for this... what is it? Oh yeah. Brainwashing.
Odds are some of the ones saying stuff like this were born that way. I touched on this in an older thread but will repeat it here for those of you who arent aware.
There is a huge difference between being born disabled and being rendered disabled. And the reactions for those rendered disabled can be much akin to CP2020's cyberpsychosis. Some people simply can not take being disabled and unfortunately some freak out.
Being born disabled is a massive advantage and for many of us its effectively a natural workaround as we do not have to adjust. This is our lives. We tend to be fairly well adapted to our conditions. Here is where you most likely get people saying its ok to be disabled. Because to them they essentially arent. Or are suffering from a form of impairment that allows them to still function normally, or close enough.
Personal example: I've never known a world that isnt constantly in motion. I am very well adjusted to that fact to the point that it effectively doesnt effect me except when Im going through periods where its more pronounced. Or in cases where high balance skills are required. Tightrope walker is not one of my job descriptions. heh.
Im not even sure how that would fit into game terms.
But I'd NEVER tell someone that they have to accept being disabled and that looking for a cure is wrong. And us 'adjusted' should NEVER tell anyone who has had a disability inflicted on them that they should accept it and not look for cures.
All that said. It is perfectly fine to be perfectly fine with your disability.
