Well, not that I've read the entire article (I was just looking for a concise list of constitutional references) but the Wikipedia article
Voting Rights in the US is informative. We see that people can vote regardless of race or gender. Obviously, then, there would be no reason for any documentation to support ones race or gender. We do see, however, that states can restrict voting to those that are citizens and 18 years or older. I don't see how requiring proof of ones compliance with prerequisites restricts their access to this freedom. I do understand the poll tax argument, I just happen to believe it's an invalid argument. After all, these people you seem to be describing certainly must have obtained some form of state issued identification when they applied for food stamps, utilized a check cashing lender, or bought a 40 at the convenience store. Just a little extra inflammation since I assume this is how you think I think anyway.
And, I wonder, if we research "mass" shootings by the mentally unstable versus fraudulently cast votes which would appear to be more prolific. Bet they both mostly occur in blue counties as well. I could be wrong, I'm not actually going to look it up. Maybe it will even become the crux of my argument.
Seriously, though, if someone thinks that mandatory psychological screening for firearms purchases is a good thing and ID for voting is bad, I don't necessarily think they're extreme or stupid or feel the need to come up with some witty Bill Maher-esque excoriation. I just think they're wrong.
