I personally don't see a thing wrong with this comparison, but in this day and age of knee-jerk responses, then I guess he'd be considered rude. Guess he should have said "vertically challenged."

Yes, but the "vertically-challenged" may not be able to jump quite as high. So they get assistance.
Just imagine if you said “n*gger midget”...lol
