Earlier quoted context omitted.
To be honest I'd never heard about voter literacy tests. I'm not in the states so the context is not something I'm aware of. I know it creates more problems than it solves, I just wish people would take the time and effort to have an informed opinion before voting. Even if that informed opinion is opposed to mine. To split hairs you don't have to be literate to name a policy.
I know it creates more problems than it solves It also strikes at the heart of what "citizen" means. See, here I thought just being a "citizen" was good enough to have the privilege to vote. But now I have to know how to read. Or name a policy. Or come up with the money to pay the poll tax. Or be a man. Or agree with you . No, the only requirement (in the U. S.) is to be a citizen and to be registered on the list of…
Like, you've already got a requirement in the US that everyone attend (public or private or home) school until they're ~16, right? So, what's wrong with requiring a civics curriculum as part of that, and then tying voting rights to a test of that civics curriculum? If people aren't passing, then they'd be temporarily disenfranchised, yes, but that'd be the government's fault/failing, not their own—and it would be up to the government to hunt them down and keep educating them until they do pass. Dragging people back (with compensation for their time) to get them qualified. Sort of like... jury duty.
Admittedly, that sounds a bit dystopian. Don't imagine cops showing up at your doorstep; just imagine it like an unpaid parking ticket. Can't get your driver's license renewed until you re-take the course; get frequent calls hounding you; etc.
