A near impossible literacy test Louisiana used to suppress the black vote

Note: there are questions about this test's authenticity. Per a note on https://www.crmvet.org/info/la-test.htm:

> [NOTE: At one time we also displayed a "brain-twister" type literacy test with questions like "Spell backwards, forwards" that may (or may not) have been used during the summer of 1964 in Tangipahoa Parish (and possibly elsewhere) in Louisiana. We removed it because we could not corroborate its authenticity, and in any case it was not representative of the Louisiana tests in broad use during the 1950s and '60s.]

Each parish in Louisiana implemented their own literacy tests, which means that there wasn't really much uniformity in the process. Another (maybe more typical) test: https://www.crmvet.org/info/la-littest2.pdf

> That literacy test seems reasonable

Except not, because any test whatsoever should be disallowed when it comes to voter registration.

I think voter registration itself should be disallowed and banned. Why should voters need to register beforehand? You should be able to just show up on election day and cast a vote. The entire process of voter registration is nothing more than a means to disenfranchise voters.

In many parts of the world voter registration is a perfectly normal practice and no one challenges it. The biggest reason for having it is that it disallows voting multiple times.

What in your opinion makes the voter registration disenfranchising for voters?

It's an additional step that must be completed well ahead of election day, making voting a two-step process. It shouldn't be necessary: you can determine on election day whether someone's already voted or not before they cast a vote.
