For the second time in less than a year, a billboard near Birmingham is carrying a racial message connected to a segregationist screed.

Posted along I-59 near Springville in St. Clair county, the billboard says "Diversity means chasing down the last white person" and includes the hashtag #whitegenocide.

The billboard appears similar to one posted near Leeds in June 2013 which read "Anti-racist is a code word for anti-white." Though the billboard was within Birmingham city limits, Leeds mayor David Miller denounced that billboard's "racist message" at the time due to its proximity to the city.

Both phrases are commonly used by the White Genocide Project, a group of white supremacist and separatist online activists. Their website refers to both slogans as "repeater phrases," words and sentences activists are encouraged to use often.

The White Genocide Project is also connected to the "swarm," and the groups follow the "Mantra," written by a segregationist named Robert Whitaker.

According to Southern Poverty Law Center research, the Mantra indicates a fear of interracial marriage and resistance to diversity, which the activists believe is unfairly pushed on "white" countries.

"The Netherlands and Belgium are just as crowded as Japan or Taiwan, but nobody says Japan or Taiwan will solve this RACE problem by bringing in millions of third worlders and quote assimilating unquote with them," the Mantra reads in part

....

"But if I tell that obvious truth about the ongoing program of genocide against my race, the white race, Liberals and respectable conservatives agree that I am a naziwhowantstokillsixmillionjews.""They say they are anti-racist. What they are is anti-white.""Anti-racist is a code word for anti-white."

The billboard appears to be owned by Dyar Signs of Trafford, Ala., but no representative was available for comment Sunday.

This fall, League of the South president Michael Hill claimed responsibility for the Leeds billboard, though he told WBHM 90.3 the sign was privately financed by a League member. AL.com has reached out to Hill for possible comment on the Springville sign.

The League has paid for several "SECEDE" billboards posted throughout the state this year, including one near Montgomery and one near Tuscaloosa.

Lamar Advertising pulled the Montgomery board after they received complaints from advertisers, though they offered Hill credit for money spent.
