re: Isn't arguing that voter ID is bigotted against minorities racist?

No.

The argument is dumb because the laws as written aren't inherently racist. In some areas they do impact minority voters, but that doesn't make them inherently racist.

It's just another ploy to keep certain voters from voting and it conjures up the poll quizzes and taxes from the Jim Crow era, so they get slapped with that label by some.
