Racist? Where the hell does that come from? Why would any particular race not be able to produce legal documentation confirming their identity at a poll booth?

11% of U.S. citizens – or more than 21 million Americans – do not have government-issued photo identification.
These voters are disproportionately low-income, racial and ethnic minorities, the elderly, and people with disabilities. Such voters more frequently have difficulty obtaining ID, because they cannot afford or cannot obtain the underlying documents that are a prerequisite to obtaining government-issued photo ID card.

Some Republicans Acknowledge Leveraging Voter ID Laws for Political Gain

People who don't participate in our society enough to acquire basic documentation required for not living on the streets are overwhelmingly not interested in voting (this accounts for a sliver of the roughly half of the nation that didn't bother to participate in the last presidential election.) If you have the means and will to visit a poll booth, you have it to get an ID, unless there are legitimately disqualifying circumstances. If you believe this isn't the case, you should be lobbying explicitly to get these people ID's more easily, not to remove the requirement at the poll booth. This documentation is already required for virtually everything else; these (hypothetical) people need your help.
This is not a difficult topic, nor is it a very nuanced one; voter ID laws in the United States are and have been overwhelmingly racist. The answers to your questions are very much easily at hand, and we don't need to argue in ignorance. I understand it can be frustrating to see evidence that you are unprepared for; yet in order to have substantive conversations, we must be ready for such evidence, and consider it when it is present.
