That's like asking "Should kids learn Pig-Latin?"

If your answer is "yes" to both, then at least you're consistent.

But if you think Pig Latin isn't going to offer them much in life, and you think cursive is, then you're just out of touch with our modern reality.

I believe that kids should learn all kinds of stuff. The more the better. Teaching pig-latin and cursive is a good thing, for fun. But NOT if it's taught as a seriously important subject where they're tested and spend days learning it.

Spend a day on it for fun. Make it lighthearted.
