If some visually impaired people insist that 80 column punched cards are the best for them, do we switch to that? Or maybe we should all work with Braille or Morse Code? I'm not convinced by lowest-common-denominator arguments. Suppose that no code representation method suits every possible programming minority; do we give up and not code at all?
Here is a counterargument: I'm not switching to idiotic tabs even if doing so saves puppies from being drowned. Not caring is a perfectly valid argument.
