What's contentious is the versions used by Republicans: make the required ID a kind of ID you can only obtain in certain locations, and then close most all of those locations in predominately black counties, or make the ID expensive or obscure or difficult to obtain for working folks. And even when it isn't racist, it's very clearly there to preserve GOP majorities:

By all means make voter ID required, just make sure the burden for obtaining it is identical across all demographics.
