Jim Crow was bad because it targeted people in the basis of a characteristic that didn’t matter: skin color. That doesn’t mean that all restrictions on voting are bad. If the restriction is based on a characteristic that does matter, like intelligence, that’s completely different.

Use that big brain of yours and try it, you might learn something about humanity (and humility)!
