I understand that the word disabled could have a sort of pejorative connotation, which is why we in the U.S. have come up with alternate expressions, such as physically challenged.
However, while I was recently watching TV news from India (as in the place on the Asian Subcontinent), a scrolling headline referred to an airline passenger who was differently abled and was provided a wheelchair upon arrival. (Not sure what the news angle was here.)
I can see our coming up with different expressions to avoid pigeonholing or denigrating people, but the whole political correctness nonsense in the U.S. is aimed at silencing anybody who disagrees with the liberal media and the liberal power merchants in Washington, D.C. and elsewhere.
Whatever his other virtues or egregious faults may be, Donald Trump would be a great president in terms of ending our nationwide PC madness (i.e., censorship), even if he does nuke Denmark, as Ted Cruz has warned.
