Rest of the delusional bigoted rant aside, people like yourself are constantly using "person in a wheelchair" to mock the idea of diversity...but when was the last time someone like that actually appeared in a mainstream movie? Literally the only one I can think of that even came close was Patrick Stewart rolling out in the Professor X's big yellow hoverchair. Which...you know...doesn't really count, seeing as the man can still walk, and the character he was playing is supposed to be unable to.
