I was referring to your class of 'undeserving' voters that you had decided to disenfranchise. If you bothered to read the amendment you would see it says a poll tax or any other tax. Furthermore, equal protection covers a lot more than that, far too much for me to explain to you now. I encourage you to read up on that. I'm glad to hear that you think that the elderly without ID (who are all inexplicably senile) and people living with their parents shouldn't vote. I think that shows pretty clearly how poorly you've thought this out, much more so than anything I could write. You're okay with disenfranchising people who live in ways you don't like. I think that's hilarious and sad.
I'm glad you now agree that these laws do in fact restrict voting rights however, as that's a start. So now that we've determined that we are imposing costs on society, we now need to look at what we get for it. Apparently the answer is some nebulous feeling of happiness for people too ignorant to realize that in person voter fraud doesn't exist.
What's strange is that early on you said something to the effect of how this only affects people who are too stupid to get an ID. Your 'benefit' however only affects people who are too stupid to learn about how voter fraud actually happens in the US. There's some amazingly horrible symmetry there.
