I sympathize with the girl, and feel terrible that there are things I can do that she cannot. I also praise her determination to lead a life like everyone else, she can influence many people that have disablities.
That said.....
I cannot play football, I do not have the physical talents to do it. Should I sue the NFL for discrimination?
I cannot dunk a basketball, I do not have the physical talents to do it. Should I petition the NBA & NCAA to lower the hoop heights?
I cannot perform open heart surgery. I so not have the mental skill to do it. I have no idea who to complain to....
Extreme cases? They sure are. Just like she has an unfortunate extreme case. If parks/ coaster designers had to cater with every unfortunate case like this, we would never be able to enjoy an amusement park again.
Many in today's society are WAY too sensitive. It has become acceptable to hand out trophies & praise for a 6th place finish. This type of action had great intentions, but has resulted in an entitlement attitude by many. Praise should not be given for a 6th place finish, just like coasters cannot be designed for every person.
