Mississippi state NAACP president Derrick Johnson was not pleased to hear the news.
"He should be viewed in the same light that we view Saddam Hussein and Osama bin Laden," he said. "The state of Mississippi should deny any vanity tags which would highlight racial hatred in this state."
Greg Stewart, a member of the SCV, said Forrest "redeemed" himself by eventually distancing himself from the KKK. But some critics don't think that's enough.
A Facebook group -- dubbed "Mississippians Against The Commemoration Of Grand Wizard Nathan Forrest" -- has launched in opposition, garnering more than 1,000 members. The group's page reads, in part:

State legislators still need to approve the series. But Rep. Willie Bailey (D), who handles license plate requests, said he doesn't have a problem with the plates.

The Sons of Confederate Voters is the "oldest hereditary organization for male descendants of Confederate soldiers," according to the groups website.

South Carolina's NAACP president criticized the event in an interview with TPM, calling it insensitive.
The other license plates in the series would feature Civil War battles that were waged in Mississippi, the AP reports. The final plate would commemorate Confederate veterans.
Mississippi sells more than 100 novelty license plates, according to the AP report. Some of the best sellers include a NASCAR plate and one that reads, "Choose Life."
