When you all get done sliding down that slippery slope into hysteria, recognize that the ability to write in cursive is a skill that could completely disappear from human knowledge and our ability to communicate wouldn't be diminished.
Nobody suggests that we should unlearn language or letters, just that we relegate cursive handwriting to the same bin we've done with calligraphy.
My point is though that cursive is far more effective than other kinds of hand-writing. It's far faster than writing block letters or calligraphy. We are "binning" the more efficient method.
