Anti-KKK laws were once common I believe.
If these people don’t normally go masked in crowded places, then they might be subject to such a law if Georgia currently has one.

This legislation was asked for by President Grant and passed within one month of when he sent the request to Congress. Grant’s request was a result of the reports he was receiving of widespread racial threats in the Deep South, particularly in South Carolina. He felt that he needed to have his authority broadened before he could effectively intervene. After the act’s passage, the president had the power for the first time to both suppress state disorders on his own initiative and to suspend the writ of habeas corpus. Grant did not hesitate to use this authority on numerous occasions during his presidency, and as a result the KKK was completely dismantled (ending the “first Klan” era) and did not resurface in any meaningful way until the beginning of the 20th century.[4]
Several of the act’s provisions still exist today as codified statutes. The most important of these is 42 U.S.C. ยง 1983: Civil action for deprivation of rights. It is the most widely used civil rights enforcement statute, allowing people to sue in civil court over civil rights violations.
