This is not the argument people are making, so I hope you aren’t making it intentionally. No one is saying that requiring voting id is inherently racist.

The argument is that requiring voting id without a commensurate effort to make sure everyone has voter id ends up disproportionately affecting minorities. These efforts are subsequently dubbed racist by political opponents because the people implementing them know this to be true and do it anyway, because they prefer the outcome that minorities are disenfranchised.

Republicans have been found in court to play these tricks with “surgical precision”, to make sure the rules they come up with impact minorities more than whites.

Another example is closing polling places so that it takes 8 hours to vote in black precincts whereas it takes 8 minutes to vote in white precincts. Yes, the act of closing a polling place is not an overtly racist thing to do. But the way in which it’s done and the actual impact make clear it is done with the intent of disenfranchising minorities.
